In this paper, we address the problem of the estimation of an underlying parameter of interest with a wireless sensor network. We assume that sensors encode (i.e. quantize) their observations at a common constant rate which, on the one hand, determines the quantization noise at the encoders and, on the other, the outage probabily experienced in the sensor-to-fusion center fading channels. We then...
This paper describes a comparative analysis between two topologies of operational amplifiers to design a 40 MS/s 12-bit pipeline analog to digital converter (ADC). The analysis includes AC and transient simulation to select the proper topology. This ADC is implemented in a 0.35 mum AMS CMOS technology with 3.3 V single power supply. The capacitors and selected operational amplifiers were scaled for...
We consider the transmission of a Gaussian source through a block fading channel. Assuming each block is decoded independently, the received distortion depends on the tradeoff between quantization accuracy and probability of outage. Namely, higher quantization accuracy requires a higher channel code rate, which increases the probability of outage. We first treat an outage as an erasure, and evaluate...
