A. Thilagam, R. Ganesh Babu · SSRN Electronic Journal · 2015
In this paper, the propose method uses adaptive time- quantized pseudorandom sampling (ATQ-PRS) as a power-saving solution compared with conventional uniform sampling. The adaptive time-quantized pseudorandom sampling (ATQ-PRS) is an advantageous processing, which is a new sampling design in which sampling regions, defined as units, are selected based on values of the variables of interest. The method is to improve the power efficiency of wireless sensor network .So it is used for SDR multi standard receiver design. The ATQ-PRS allows aliases attenuation leading to a relaxed receiver baseband stage. Adaptive Time Quantized pseudo Random Sampling technique in the multi stand radio receiver for the baseband power consumption Due to its ability to reduce replicas’ power levels, ATQ-PRS reduces the design constraints on receiver components. Applied on the baseband stage of a multi standard radio receiver, ATQ-PRS allows decreasing the anti aliasing filter order, as well as reducing the sampling frequency. This feature leads to saving up to 40% of baseband power consumption.
