Abstract
Recently Cooperative communication is proposed for the 4th Generation of mobile Communication i.e. LTE-Advanced. Cooperation is expected to enhance data rates and coverage significantly as compared to existing 3G technologies. Cooperative communication enables single antenna mobiles in a multi-user environment to share their antennas and generate a virtual multiple-antenna transmitter that allows them to achieve transmit diversity & to exploit the benefits of multiple-input multiple-output (MIMO) systems in a cost effective manner. The scope of this research paper is to investigate Decode and Forward cooperative communication Protocol by analyzing its Bit Error Rate (BER), throughput and outage probability.
Keywords-components - Decode and forward (DF), Amplify and Forward (AF), Bit Error Rate (BER), Multiple Input Multiple Output (MIMO), Maximum Ratio Combining (MRC).
1. INTRODUCTION
Wireless communication has grown rapidly over the last two decades and this trend is expected to continue in the future as well. Today, there is an increasing demand for high data rates in order to support high speed interactive internet services and advanced multimedia applications such as mobile TV, online gaming etc [1]. However, the transmission over wireless channel of high rate (i.e. bandwidth) demanding services faces fundamental limitations due to impairments inflicted by the wireless channel due to path loss, shadowing and fading effects. These impairments can be compensated by various ways such as by increasing transmit power or bandwidth or applying powerful error control coding (ECC). However, power and bandwidth are very scarce and expensive radio resources while ECC yields reduced
