Abstract: Methods, systems, and devices for wireless communications are described. A wireless communication system may support techniques for correlation-based hardware sequences for layered decoding. In some cases, a user equipment (UE) may partition layers of a submatrix associated with a parity check decoding procedure into a first set of layers and a second set of layers. The UE may sort each set of layers into a respective set of layer orders (e.g., a first set of layer orders and a second set of layer orders) based on an associated set of correlation values. The UE may combine the first set of layer orders and the second set of layer orders to obtain a set of combined layer orders and may select a decoding schedule from a set of decoding schedules used for decoding each of the combined layer orders based on respective schedule lengths for the set of decoding schedules.

Abstract: Systems and methods for performing real-time feedback communication in accordance with various embodiments of the invention are disclosed. In many embodiments, instantaneous encoding is utilized for transmitting symbols from a streaming source over a DMC with feedback. In certain embodiments, instantaneous encoding is performed during the arriving period of the symbols. At time t, the encoder and the decoder calculate the priors of possible symbol sequences using the source distribution and the posteriors at time t?1. In a number of embodiments, the encoder and decoder then partition the evolving message alphabet into groups, so that the group priors are close to the capacity-achieving distribution. In contrast to the SED rule for symmetric binary-input channels, partitioning processes in accordance with several embodiments of the invention utilize group priors instead of group posteriors for the partitioning.
