Diversity for Body Area Networks

In this paper a review of diversity for body-centric communications is presented. On-body communication channels are affected by fading whose effects need to be mitigated. Recently, diversity techniques for on-body systems have been experimentally analyzed. Results on space diversity at 2.4 GHz have been obtained, which proved the effectiveness of diversity scheme implementation. The diversity performances have been evaluated in terms of diversity gain, power imbalance and envelope correlation coefficients between the two receiving channels, and finally by the analysis of the cumulative distribution function of the normalized received power.
