ABSTRACT

in this project, we investigate the two-way satellite relaying (TWSR) system with 2 antennas at Base Stations [BSs]. The satellite used is a bend-pipe satellite which receives signals over the uplink and broadcasts these signals with some transponder gain. The signal undergoes self interference during transmission which can be overcome by having perfect knowledge of the uplink and downlink Earth Stations [ESs]. But this knowledge about the uplink and downlink ESs are difficult to produce due to reciprocity issue and transmit power limitations. So, we investigate the Channel State of Information (CSI) with Weibull Distribution and found that the design of training protocol for two-way satellite relaying is in correct state under the practical involvement of CSI estimation. We even found that both the ESs transmits orthogonal training sequence which fulfils the value of CSI for self-interference cancellation. With the help of analytically demonstrated effect of CSI estimation with Weibull Distribution over the performance of the TWSR system, we obtain reduced bit error rate and average capacity of the scheme.
