On Optimal Data Detection for UWB Transmitted Reference Systems

GLRT receivers for UWB systems

“…On one side we derive the GLRT detectors for TR and DTR and compare their performance. Note that the detector for TR has already been investigated in [4] and [3]. However in [4] the signal model is different from that adopted here, while in [3] the incoming pulses have all the same shape, which is known at the receiver.…”

“…This simple mechanism is extended in [2], [3] where the average of the channel responses to several reference pulses is used as a template waveform. The generalized likelihood ratio test (GLRT) detector for TR systems is investigated in [3], [4] under different signal and channel model assumptions.…”

Ultra-Wideband Communications using Hybrid Matched Filter Correlation Receivers

“…The approximate BEP expression in (20) can be used to obtain an optimal integration interval, equivalently Q in (18), for that purpose.…”

“…1 as the summation of a signal and a noise term. Then, the information bit is estimated as the sign of the integral of the multiplication between the despread signal and its delayed version: (18) where Q is an integer that determines the integration interval. Note that the detection algorithm is basically the conventional delay-and-multiply operation applied on the despread signal r(t).…”

“…There can be both inter-frame interference (IFI) and interference between the reference and the data pulses. Almost all of the previous studies ignore the effects of those interference terms [12], [14], [17], [18] 1 . In this paper, we introduce a new differential receiver structure that has a performance similar to that of [8].…”
