Certain aspects of the present disclosure generally relate to techniques for efficient, high-performance decoding of low-density parity check (LDPC) codes, for example, by using an adjusted minimum-sum (AdjMS) algorithm, which involves approximating an update function and determining magnitudes of outgoing log likelihood ratios (LLRs). Similar techniques may also be used for decoding turbo codes. Other aspects, embodiments, and features (such as encoding technique) are also claimed and described.

A mobile device includes a display, a mobile-communication modem including a Viterbi decoder (VD) configured to decode a tail biting convolutional code (TBCC)-encoded data, a memory coupled to the mobile-communication modem, and a wireless antenna coupled to the mobile-communication modem and to receive a Physical Downlink Control Channel (PDCCH). The VD is configured to: receive data encoded by TBCC; select a candidate to initiate a training section; determine final path metric (PM) values of possible states at a last step of the training section; determine a PM-related value based on the final PM values of the possible states; and determine an early termination of a decoding for the candidate based on the PM-related value.

Control information for configuring an audiovisual device to present multimedia content according to a first service type may be generated. A method may include generating first control information for configuring an audiovisual device to decode a multimedia stream, generating first data that indicates a structure of the first control information, and transmitting the first data and the first control information. The first control information may be generated according to a first protocol version. Second data and second control information may be similarly generated and transmitted according to a second protocol version. Disclosed techniques may facilitate receiving devices to determine whether they support received wireless transmissions and decode the transmissions based on the control information.

A local area network (LAN) backbone is implemented within an environment such as a self-contained environment (e.g., an automobile, an aircraft, a train, a ship, and/or any other environment). The LAN backbone is affected by AWGN, NBI, and/or impulse noise (noise). The LAN backbone supports communications based on an Ethernet communication protocol (e.g., a 1000Base-T1 based system that includes at least one single twisted pair). A device receives a first LDPC coded signal via the LAN backbone and decodes it to recover an input signal of a control system. The device also uses soft information generated during the decoding to compensate for the noise affecting the LAN backbone and then processes the input signal to generate a control signal for the control system. The device then and encodes the control signal to generate a second LDPC coded signal and transmits the second LDPC coded signal via the LAN backbone.
