Bit-Error-Rate Analysis of UWB Radio Using BPSK Modulation Over Inter-Chip Radio Channels for Wireless Chip Area Networks

Wireless Chip Area Networks (WCAN) signifies a new development in wireless communications, where wireless interconnections among different cores within a chip (intra-chip) or among different chips within a module (inter-chip) can be realized. In this paper, the authors analyze Bit-Error Rate (BER) of an Ultra-WideBand (UWB) radio with Binary Phase-Shift Keying (BPSK) modulation over an inter-chip wireless radio channel. Specifically, a novel technique of dynamically shifting an integral window is proposed to reduce the effects of Inter-Symbol Interference (ISI). BER expressions are analytically derived and verified by Monte Carlo simulations.
