— Recent published work suggests that correlative coding can improve OFDM performance by several dB. This work, however, does not consider fully a symbol error rate performance m...
—In this paper, we present a novel multi-carrier spread spectrum (MCSS) system which uses Parallel Sequence Spread Spectrum (PSSS) as its spreading transform. This technique call...

: This paper is concerned with a randomized OFDM (R-OFDM) scheme. The basic principle is to apply a scrambling operation to several OFDM frames. With a proper design strategy, the ...
Abstract— The path and antenna correlations significantly degrade the system capacity in spatially-multiplexed multiple-input multiple-output (MIMO) orthogonal frequency-divisio...
