Abstract: A receiver for signals, comprising an amplifier arranged to receive and amplify the signals received by the receiver. The receiver also comprises a linearizer arranged to linearize the amplitude value of the output signals from the amplifier. In the receiver, the linearizer is arranged to perform said linearizing by means of determining actual and desired values of a statistical function for the amplitude values of the output signals from the amplifier and to replace the amplitude values of the output signals from the amplifier with amplitude values which have the same desired values of the statistical function. In embodiments of the receiver, the statistical function is the cumulative distribution function.

Abstract: In an advanced adaptive modulation and coding (AMC) scheme, the code rate and the parity-check matrix (PCM) for low-density parity-check (LDPC) codes are adapted according to modulation formats and variable-iteration receivers. The degree distribution for the PCM adaptation is designed by heuristic optimization to minimize the required SNR via an extrinsic information transfer (EXIT) trajectory analysis for finite-iteration decoding. The method uses dynamic window decoding by generating spatially coupled PCM for quasi-cyclic LDPC convolutional coding. The method also provides a way to jointly optimize labeling and decoding complexity for high-order and high-dimensional modulations.

Abstract: Methods and apparatus for providing soft and blind combining for PUSCH acknowledgement (ACK) processing. In an exemplary embodiment, a method includes soft-combining acknowledgement (ACK) bits received from a UE that are contained in a received sub-frame of symbols. The ACK bits are soft-combined using a plurality of scrambling sequences to generate a plurality of hypothetical soft-combined ACK bit streams. The method also includes receiving a parameter that identifies a selected scrambling sequence to be used. The method also includes decoding a selected hypothetical soft-combined ACK bit stream to generate a decoded ACK value, wherein the selected hypothetical soft-combined ACK bit stream is selected from the plurality of hypothetical soft-combined ACK bit streams based on the parameter.
