Data-aided (DA) signal-to-noise ratio (SNR) estimation is required especially at low SNR. The conventional maximum likelihood (ML) DA SNR estimator requires perfect carrier phase estimation and frequency recovery. In this paper, we propose a novel carrier frequency robust DA SNR estimator with its improved variant using autocorrelation of received MPSK symbols. Computer simulations are used to examine...
The increase in user amount and voice traffic puts a huge pressure on GSM/EDGE networks especially within populous countries. A newly proposed concept, multi-user reusing one slot (MUROS), would help operators in densely populated cities to alleviate the strain on their networks. The key idea of MUROS is to multiplex two or more users onto one time slot. We improved one downlink (DL) MUROS solution,...
