Space diversity formula
WebSpace–Time Coding (STC) was first introduced by Tarokh et al. [22,25,26] in 1998 as a novel approach for providing transmit diversity for the multiple-antenna fading channel. The Space–Time Trellis Code (STTC) is a popular variant of space–time codes that can be used to improve the performance of the wireless communication systems over ... WebSpace diversity is an alternative or additional form of protection from the effects of multipath fading. 2 s Its effectiveness depends upon the fact that multipath propagation …
