Abstract :
In this paper, we consider two enhancements for self-heterodyne OFDM (Self-Het OFDM): subcarrier pairing and smart carrier positioning (SCP). We analyze their performance over a practical 60 GHz indoor RF channel. This channel deviates from the standard AWGN and Rayleigh fading models for Line of Sight (LoS) and Non LoS. We show that for NLoS channels they can jointly improve the diversity order and performance by 7.7 dB at BER of 10-2, when compared to the standard self-het OFDM. Similar improvements are observed for channels with strong LoS components.
