Title: BEM (Basis Expansion Model) Receivers for Severe Doubly Selective Fading Communication Channels

Time: 13:00-13:30, Thursday, 10 August

Abstract: High mobility broadband communication channels tend to suffer from large Doppler spread in addition to multipath fading. Such doubly selective fading becomes more severe when the carrier frequency bands move higher to mm-wave or THz bands. To build a communication receiver which is able to track the fast time variation of the channel states without requiring excessive pilot overheads, and to handle the severe inter-symbol interference or inter-carrier interference (depending on whether single-carrier or multi-carrier signalling is employed), is a major engineering challenge. I will share recent results in advancing this research by exploiting BEM channel modelling, pseudo-pilot, joint channel estimation and equalization, and other concepts. Once the detrimental effects of doubly selective fading are mitigated, channel coding can take over to enjoy the enhanced time/frequency diversity in the detected data symbols.

Title: High-Speed LFSR Decoder Architectures for BCH and GII Codes

Time: 13:30-14:00, Thursday, 10 August

Abstract: In literature, {\bf PIBMA}, a linear-feedback-shift-register (LFSR) decoder, has been shown to be the most efficient high-speed decoder for Reed-Solomon (RS) codes. In this work, we follow the same design principles and present two high-speed LFSR decoder architectures for binary BCH codes, both achieving the critical path of one multiplier and one adder. We identify a key insight of the Berlekamp algorithm that iterative discrepancy computation involves only even-degree terms.  The first decoder separates the even and odd-degree terms of error-locator polynomial to iterate homogeneously with discrepancy computation. The resulting LFSR decoder architecture, dubbed {\bf PIBA}, has $\lfloor\frac{3t}{2}\rfloor+1$ processing elements (PEs), each containing two registers, two multipliers, one adder, and two multiplexers (same as that of {\bf PIBMA}), which compares favorably against the best existing architecture composed by $2t+1$ PEs. The second one, dubbed {\bf pPIBA}, squeezes the entire error-locator polynomial into the even-term array of the first one to iterate along with discrepancy computation, which comes at the cost of a controlled defect rate. {\bf pPIBA} employs $t+1+f$ systolic units with a defect probability of $2^{-q(f+1)}$, where $q$ denotes the finite field dimension and $f$ is a design parameter, which significantly reduces the number of PEs for a large correcting power $t$.

The proposed architectures can be arbitrarily folded to trade off complexity with latency, due to the systolic nature.

GII decoding has been notorious for the composition of many seemly irrelevant functional blocks. We are motivated by the unified framework {\bf UPIBA} which can be reconfigured to carry out both error-only and error-and-erasure decoding of RS codes in the most efficient manner. We devise a unified LFSR decoder for GII-RS, GII-ERS (referring to erasure correction of GII-RS codes), and GII-BCH codes, respectively. Each LFSR decoder can be reconfigured (but not multiplexed) to execute different functional blocks.
