Turbo Decoder Performance Analysis in Multiuser LTE+ Systems

Abstract

Survey on the LTE+ wireless network, aimed at addressing a series of enormous technological criteria and problems. It is difficult to reliably measure, monitor, and forecast fast time-varying coefficients of fading. A multiuser system is a network with increased bandwidth and energy conservation. The advantage of such systems can be enjoyed with the retention of CSI precision. CSI inaccuracy is caused due to losses during channel estimation and channel aging in multiuser systems. This paper highlights the modulation order change effect on Eb/N0 during turbo decoding processes. It is seen from the results that as modulation order is increased, BER also increases. The system performance is improved by 15 % as compared to the literature reviewed.
