Abstract
Wireless link in mobile cellular communication system is experienced by large and small scale fading. Since the link is non line of sight (NLOS), therefore, severely affected by multipath fading. In a two-hop wireless links, each link is affected by fading and noise degrades the overall performance of the communication system. In this paper, performance of two- hop links is analyzed under Rayleigh and Nakagami-m fading environments separately for QPSK and 8-PSK modulation schemes. In this paper zero-forcing adaptive equalizer is used on two-hop wireless links to enhance the performance of the system. Here we find that zero-forcing adaptive equalizer works better for QPSK scheme and Nakagami-m fading channel compared to 8-PSK scheme and the Rayleigh fading channel.
