"Lightweight hierarchical error control coding (LHECC)" is a new class of nonlinear block codes that is designed to increase noise immunity and decrease error rate for high-performance chip-to-chip and on-chip interconnects. LHECC is designed such that its corresponding encoder and decoder logic may be tightly integrated into compact, high-speed, and low-latency I/O interfaces. LHECC operates over a new channel technology called multi-bit differential signaling (MBDS). MBDS channels utilize a physical-layer channel code called "N choose M (nCm)" encoding, where each channel is restricted to a symbol set such that half of the bits in each symbol are set to one. …

Multiple Input Multiple Output (MIMO) systems have received enormous attention by researchers as they can provide a roughly linear increase in capacity of wireless communications systems by using multiple transmit and receive antennas. Even with the larger raw data rates provided by MIMO, the throughput of these systems can be limited by the number of users (or networks) sharing the medium. This paper shows how multiple users (or networks) transmitting simultaneously can be represented as a MIMO system with a larger number of transmit than receive antennas. After reviewing existing decoders for such a MIMO system, this paper then proposes …
