title = "Towards time-quantized random sampling for multistandard receiver baseband stage",
abstract = "In this paper, the ability of time-quantized random sampling (TQ-RS) to reduce aliases is discussed. Authors present simulation results of power spectrum density of a time-quantized random sampled signal. The oversampling ratio impact on alias reduction is outlined. TQ-RS application is proposed for baseband stage design of software defined radio receiver supporting the GSM, the UMTS and the IEEE802.11a standards. Obtained design results are compared to design results considering the uniform sampling. This comparison shows that the anti-aliasing filter order has been reduced from 4 to 3 and the maximal gain of automatic gain control is decreases with at least 12 dB. A test setup for data acquisition system with TQ-RS is detailed. Validation results confirm the targeted performances in terms of signal-to-noise ratio (SNR) of TQ-RS acquisition. The SNR is equal to 53.13 dB in TQ-RS compared to 54 dB in uniform sampling.",
