摘要：

Transmitted-reference impulse radio with autocorrelation receiver (TR-IR/AcR) generally requires wideband analog delay line (WADL) with length of several tens nanoseconds. To maximally reduce the length, we propose a TR-IR system based on selective combining, which intelligently selects integration regions for symbol detection. It was shown that when the WADL with a total length of 8 ns is employed, the proposed system has a signal-to-noise ratio gain of 0.5 dB, 2.3 dB, 2.3 dB and 3.7 dB over the TR-IR/AcR at bit-error-rate of 10(-5) for ultra-wideband channel models CM 1 similar to 4, respectively.
