Abstract
One of the major challenges in wireless communications, especially in urban area, is to detect the digital data under different fading environment and additive white Gaussian noise (AWGN). In a two-hop wireless links, each link is affected by fading and noise which degrades the overall performance of the communication system. In this paper performance of two-hop link is analyzed under Rayleigh and Nakagami-m fading environments separately for 8-PSK and 16-QAM modulation schemes. The objective of the paper is to observe the relative impact of two fading environments on the two above mentioned modulation schemes if no combining scheme or error correction measure is taken on the repeater station.
