Abstract

Improving the performance of relay systems using patterns such as power allocation requires access to instantaneous channel coefficients. extraction of this information is always prone to errors and this error increases the undesirable portions of the received signal in the receiver, in addition to disrupting the relay system optimization pattern. the Fixed and Variable gain relays, according to the type of operation, have different effect on the estimation error of channel coefficients. in this paper, with a detailed examination of the effect of the estimation error of channel coefficients according to the pattern of estimation, suitable power allocation is proposed to reduce the effects of undesirable segments in the Fixed and variable Gain operation. Reference papers in this matter for power allocation always use second-order statistical data but in this paper, the estimated coefficients will be used. due to the complexity of the performance of the Variable gain relay in control of the interference channel effect in two-way relay, the closed form for power allocation is presented.
