An improved form for Switched Combining (SwC) with on-body cooperative communications is presented, particularly suited to the ‘everyday’ wireless body area network (BAN) wireless channel. Two and three-branch cooperative coherent SwC is analyzed theoretically and empirically and compared with cooperative coherent selection combining (SC), and a previous switched combining implementation. New expressions...
Cooperative diversity using switched combining, incorporating transmit power control (PC), is investigated for wireless body area networks (BANs). Outage probability and switching rate are derived from extensive empirical measurements, along with savings in circuit power consumption using simple ‘sample-and-hold’ PC in conjunction with switch-and-examine combining (SwC). Theoretical approximation...
A non-data-aided near maximum likelihood (NDA-NML) symbol timing estimator is applied to cooperative communications in fast flat-fading conditions. The performance of a three-node detect-and-forward cooperative communication system is evaluated operating in fast Rayleigh fading channels using various signal constellations with and without synchronization. Timing errors have significant effect on performance...
