Performance of Smart Grid Dynamic HAN with RQAM and GMSK Modulation

In smart grid communications, home area network (HAN) plays an important role in managing data transmission among communicating devices through a smart meter. Performance of the network depends on the efficiency of modulation schemes used in the communicating devices such as rectangular quadrature amplitude modulation (RQAM) and Gaussian minimum shift keying (GMSK). Saleh-Valenzuela (S-V) and Weibull fading channels are appropriate models for indoor communication channels. Average symbol error rate (ASER) and average channel capacity (ACC) performance of indoor dynamic HANs with communicating devices using RQAM and GMSK are analyzed for these channel models. Numerical results are presented to demonstrate the effect of traffic intensity, number of active devices in HAN, and the modulation types with parameters of practical interest.
