Inheriting all merits of a multiuser transmitted reference (MTR) ultra-wideband (UWB) transceiver, a biorthogonal MTR (BO-MTR) transceiver for high datarate communication has been recently reported. It utilizes 4-ary biorthogonal signaling to carry two bits of each user's information in amplitude and position of the data pulse simultaneously. Assisted by a simple coding scheme, both bits are independently decoded using low complexity correlators whose templates are obtained from aggregated reference signals spanning multiple symbol intervals. This paper further studies its performance in different scenarios. In a multipath-free fading scenario, the receiver's symbol error rate (SER) performance is shown to be optimal while no complex joint detection of two bits is necessary, and the bit error rate (BER) performance of each detector is balanced. For multipath channels, when channel parameters are either deterministic and estimated with errors, or random in Rician distribution, the Chernoff bounds are derived for BER of each detector. A much tighter bound is also provided according to the property of the complementary Gaussian distribution function.
