Abstract

This research article presents an innovative approach based on analog network coding (ANC) in conjunction with space time block coding (STBC) which is termed as space time analog network coding (STANC). The STANC investigated as an affective network coding strategy to combat the effects of shadowing and path loss in wireless networks. The another objective of this research work is to evaluate the impact of relay location on system performance in increasing shadowing effect due to increasing tall structure like multistory building in metropolitan area. The performance of the proposed system is analyzed in terms of symbol error rate (SER), STANC gain and ergodic capacity using analytical expressions. Moment generating function approach is used to drive the SER for M-PSK modulated signals. The approximate closed-form expression of ergodic capacity is presented using the derived mean and second moment for STANC based cooperative system. Rician shadowed model is used which efficiently evaluate the effect of shadowing as compared to other fading models given in the literature which is the main advantage of this model. Numerical results signify that the approximated analytical expressions derived can be effectively used for performance improvement under path loss and shadowing effect as compared to simple ANC based system.
