A modified NCO based LSPF-DPLL Phase Resolver for wireless communication

Abstract

With rapid advancements in communication technologies, SG is already in the reckoning. Communication systems that can serve low error rates at minimum delay are the need of the hour. DPLL based receivers are popular in modern day communication setups. Such standalone receivers based on Least Square Polynomial Fitting (LSPF) and Zero Crossing (ZC) techniques have been recently proposed. These systems exhibit satisfactory error performance at the cost of degraded time performance involving intensive computations. A Modified NCO based LSPF-DPLL Phase Resolver with superior error and time performance as compared to existing LSPF-DPLL is presented here.
