A New Formula for the BER of Binary Modulations With Dual-Branch Selection Over Generalized-K Composite Fading Channels
Error performance is one of the main performance measures and derivation of its closed-form expression has proved to be quite involved for certain systems. In this paper, a unified closed-form expression, applicable to different binary modulation schemes, for the bit error rate of dual-branch selection diversity based systems undergoing independent but not necessarily identically distributed generalized-K fading is derived in terms of the extended generalized bivariate Meijer G-function. In recent times, different diversity schemes have taken up an important position in the wireless communication systems. The main reason behind this is that these different diversity schemes allow for multiple transmission and/or reception paths for the same signal.
