A method of decoding a plurality of diverse signals for low-density parity-check (LDPC) decoders that takes advantage of signal diversity. The method allows for the combining of soft-decision LDPC encoded non-coherently modulated signals, which is in contrast to existing approaches where hard decision combining is used for non-coherently modulated signals. The method includes the steps of inputting each diversity signal into a unique demodulator, and calculating the LLR of each demodulated signal. When the diverse demodulated signals are combined into a single combined signal, each bit of the combined signal is selected according to the value of either the highest LLR value of each bit across the demodulated signals or according to the sum of the LLR of each bit across the demodulated signals.

A beamforming device is provided. The beamforming device comprises: a beam deriving unit for deriving, among multiple reception beams, a first reception beam receiving, from a terminal, the first largest reception signal and a second reception beam receiving, from the terminal, the second largest reception signal; and a control unit for estimating the direction of the terminal on the basis of a ratio value between the size of the reception signal received through the first reception beam and the size of the reception signal received through the second reception beam.

There is provided an antenna arrangement for a radio transceiver device for simultaneous use of two polarization directions. The antenna arrangement comprises at least two baseband chains. The antenna arrangement further comprises a first set of antenna elements of a first polarization direction, and a second set of antenna elements of a second polarization direction. The antenna arrangement comprises an analog distribution network operatively connecting the at least two baseband chains to both sets of antenna elements. All of the baseband chains are operatively connected to each respective antenna element of the first set and to each respective antenna element of the second set via the analog distribution network.

The apparatus may be further configured to determine, for each of a subset of the received beams, a log likelihood ratio (LLR) for coded bits of the broadcast information. The apparatus may be further configured to decode the broadcast information associated with each of the subset of the received beams, and determine a refined receive beam direction based on the determined LLRs and based on whether the broadcast information associated with each of the subset of the received beams fails to decode or is successfully decoded.

A receiver and a detecting method thereof are provided. The receiver includes a plurality of antennas receiving a transmitted signal through multiple paths; and an equalizer collecting a plurality of sample signals by reflecting signals received in other antennas in the signals received in the plurality of antennas, and detecting a symbol of the transmitted signal by combining the plurality of sample signals that are collected with each other.

A base station receives signals transmitted from one terminal in cooperation with another base station and performs synthesis processing of the received signals of the other base station and the received signals of the local base station. In the base station, a determination circuit determines necessity of synthesis processing using the received signals of the local base station at the time of the first transmission of the terminal. A base station-to-base station communication circuit transmits a message requesting forwarding of the received signals to the other base station in a case where the synthesis processing is determined to be necessary and receives the forwarded signals that are forwarded from the other base station at the time of retransmission of the terminal. A synthesis circuit synthesizes the forwarded signals from the other base station and the received signals of the local base station in a case where the synthesis processing is determined to be necessary.

Certain aspects provide a method for decoding information sent via a wireless transmission. The method generally includes receiving an indication of an association between a first decoding candidate and a second decoding candidate, monitoring the first decoding candidate in a search space of a first set of resources, the first decoding candidate received from a wireless node, and monitoring the second decoding candidate in a search space of a second set of resources, the second decoding candidate received from the wireless node, wherein the monitoring of the second decoding candidate is based on the association between the first and second decoding candidates.

Aspects of the disclosure are directed to providing signals utilizing two or more sources. As may be implemented in accordance with one or more embodiments, a method and/or apparatus involves processing respective signals carrying broadcast data provided by different receiver circuits that respectively receive the same broadcast data. The signals received from the respective receiver circuits are equalized, and corresponding sets of the broadcast data from each of the equalized signals are selectively combined to provide a combined signal carrying the broadcast data. This approach may be used, for example, to generate broadcast data utilizing source data from two or more receivers, such as may be received on different signal mediums (e.g., over-the-air digital radio and Wi-Fi digital radio), and therein providing enhanced reception.
