Abstract:Space-time block codes are considered as one of the prominent technologies for spatial diversity which is widely used to improve wireless system performance. However, an OFDM system with space-time block codes needs multiple fast Fourier transforms (FFT) posing an adverse effect on system computational load as the number of antennas and sub-carriers grows. Therefore, in this paper we employ a single FFT scheme for the implementation of multiple transceivers on field programmable gate array (FPGA). The results … Show more
