Body-centric communications is an important part of fourth-generation personal communications systems. Like the mobile cellular communication channel, on-body communication channels are affected by fading. In this paper, the effect of diversity for on-body communication channels is investigated. Measurements were taken in both an anechoic and typical indoor environments, with random body movements...
High diversity gains achieved for the on-body channels suggest that multipath due to the environment and the body both play a role in the propagation. The correlation of the diversity branches is low for most of the channels, which suggests that the diversity can provide very good improvement, if the power imbalance is carefully dealt with. The uplink and downlink diversity and correlation is reciprocal...
