The method includes decoding first data wherein an amount of the first data received within one transmission time interval reaches a target amount; if decoding of the first data succeeds, decoding second data that comprises the first data and additional data received during a unit section within the one transmission time interval; if decoding of the second data succeeds, transmitting the decoded second data; and terminating decoding of data received after receiving the second data within the one transmission time interval.

A digital signal receiver comprises an iterative decoder configured to decode its input signal using an iterative decoding algorithm, a signal quality detector, configured to detect signal quality of the input signal of the iterative decoder; a power consumption monitor, configured to detect a parameter indicating power consumption of the iterative decoder; a voltage regulator, configured to adjust a supply voltage of the iterative decoder to maintain it within a preset supply voltage range, based on the detected parameter indicating the power consumption of the iterative decoder; and an iteration controller, configured to adjust a maximum iteration number of decoding based on the signal quality of the input signal of the iterative decoder.

A transmitting apparatus is provided. The transmitting apparatus includes: an encoder configured to generate a low-density parity check (LDPC) codeword by LDPC encoding based on a parity check matrix; an interleaver configured to interleave the LDPC codeword; and a modulator configured to map the interleaved LDPC codeword onto a modulation symbol, wherein the modulator is further configured to map a bit included in a predetermined bit group from among a plurality of bit groups constituting the LDPC codeword onto a predetermined bit of the modulation symbol.

A signal transmission method is performed by a base station. The method includes: determining, a first carrier signal that is to be sent in a first cell on a first carrier and a second carrier signal that is to be sent in a second cell on a second carrier; mapping, the first carrier signal and the second carrier signal to N physical ports of an RRU, so that within a same OFDM symbol, a type B symbol used to transmit a pilot in the first carrier signal and a type B symbol used to transmit a pilot in the second carrier signal are mapped to different physical ports, and a total power of signals sent on each of N physical channels is not greater than a rated power of the RRU; and sending, the first carrier signal and the second carrier signal through the N physical ports.

Techniques for improving the latency or processing performance of an error correction system are described. In an example, the error correction system implements LDPC decoding and uses an early termination rule to determine whether the LDPC decoding should be terminated prior to reaching a maximum number of iterations. The early termination rule involves various parameters that relate to the syndrome of the decoded LDPC codeword at each iteration. These parameters include the number of the current decoding iteration and the weight of the syndrome at the current iteration. For example, the early termination rule specifies that the LDPC decoding should be terminated prior to the maximum number of iterations either when the weight of the syndrome is zero, or when the current number of iterations reaches an iteration number threshold and the weight of the syndrome equals or exceeds a checksum threshold.

A method for operating a mobile communication network includes identifying link processing jobs running on one or more entities in the mobile communication network which cause an increase of data transmission delay in a communication link between the radio access network and a core network of the mobile communication network. One or more of the identified link processing jobs is selected. Link parameters of the selected link processing jobs of the communication link are adapted depending on latency requirements of a service using the communication link.

Apparatuses, systems, and methods are disclosed for stochastic interference cancellation. A digital signal processor decodes a set of transmitted signals based on a set of received signals. A projection module updates a subset of a set of estimated signals based on error information and on a corresponding subset of mapping information. Error information is based on the received signals and the set of estimated signals. Mapping information indicates how the received signals are affected by the transmitted signals. A stochastic update module adjusts the set of estimated signals based on generated noise. An interference cancellation module updates the error information based on the adjusted estimated signals.

A device system and method is provided for early termination of a decoding process performed at a receiving user device. A user-specific message may be received, from a communication channel shared by multiple user devices. The user-specific message may include an error correction codeword generated by shifting an original codeword by an offset codeword uniquely associated with a target user device. The error correction codeword may be shifted based on an offset codeword uniquely associated with the receiving user device. The received message may begin to be decoded. If the receiving device is the target device, the offsets respectively associated therewith are equal and cancel, and the original message is decoded to completion. If, however, the receiving device is not the target device, the offsets respectively associated therewith are not equal and combine to form an above threshold decoding error and decoding is terminated before completion.

Embodiments described herein provide a system for dynamically selecting a pre-processing scheme for an LDPC decoder. The system includes a receiver configured to detect transmission of a first data packet and receive a first set of data bits corresponding to a first portion of the first data packet. The system further includes a histogram generator configured to calculate log-likelihood ratios for each data bit from the first set of data bits, and generate a histogram based on the calculated log-likelihood ratios. The receiver is configured to continue receiving a second set of data bits corresponding to a second portion of the first data packet. The system further includes a selector configured to activate or inactivate a log-likelihood ratio pre-processing scheme on the received second set of data bits based on characteristics of the histogram.
