Abstract

This paper presents an efficient and simple hardware design of signal to noise ratio (SNR) estimator for DVB-S2 system. The estimator investigates the distribution of the received symbols by simply using two comparators and a counter, and calculates the address of an LUT where the corresponding SNR value is located. In this paper, we demonstrate the functional and timing simulation results of the FPGA implementation of proposed structure.
