Abstract :
This paper investigates the power and rate allocation policy in body-area-networks (BANs) when using MIMO antenna arrays. The on-body channel model which considers different propagation mechanisms in different spatial subchannels is derived by using the measured statistical parameters. At low SNR range, the discrete and continuous schemes yield similar spectral efficiency performance. Also, the achievable Shannon capacity is lower than the equivalent Rayleigh channel.
