Unified Analysis of UWB Transmitted-Reference Schemes in the Presence of Narrowband Interference

Transmitted-Reference (TR) signaling, in conjunction with an Autocorrelation Receiver (AcR), offers a low-complexity alternative to Rake reception in ultrawide bandwidth systems. This paper provides a unified performance analysis of various TR schemes by developing an analytical framework based on the sampling expansion approach. Specifically, the authors derive the uncoded Bit Error Probability (BEP) of different TR signaling schemes, including TR and Differential TR (DTR) signaling valid for a broad class of fading channels. They consider both AcRs and modified AcRs with noise averaging. They further develop a quasi-analytical method as well as an approximate analytical method to extend the BEP analysis to include the effect of NarrowBand Interference (NBI).
