A New Hybrid Space-Time Block Codes and Spatial Multiplexing Scheme with Precoding
— We present a new hybrid scheme which combines space-time block codes (STBC) and spatial multiplexing (SM) to achieve both diversity and spatial multiplexing gain. We design a n...

Improved Equalization For Coded, Zero-Padded OFDM (ZP-OFDM) Systems
Abstract— Zero-padded OFDM (ZP-OFDM) systems have recently been adopted in certain wireless systems, such as the multiband-OFDM based WiMedia standard, instead of the more common...

Low-Complexity, Low-Memory EMS Algorithm for Non-Binary LDPC Codes
— In this paper, we propose a new implementation of the EMS decoder for non binary LDPC codes presented in [7]. A particularity of the new algorithm is that it takes into account...

Lowering Error Floor of LDPC Codes Using a Joint Row-Column Decoding Algorithm
Low-density parity-check codes using the beliefpropagation decoding algorithm tend to exhibit a high error floor in the bit error rate curves, when some problematic graphical stru...
