| Popis: | The wireless fading channel creates unknown impairments on the transmitted signal. Multiple antenna systems have been well studied for providing diversity and/or coding gain over fading channels. In this paper, a new simpler form of signaling scheme is developed for Multiple Input Multiple Output(MIMO) channels. At the receiver, minimum Pearson distance based detector (MPD) is employed with Slepian’s algorithm, which uses a unique codebook design to estimate the transmitted code word with lesser computations. The scheme is developed for BPSK/QPSK 2x2 and 4x4 MIMO systems over time invariant Rayleigh fading channel. Simulations show significant gains in terms of Bit Error Rate (BER) performance and computational complexity when compared with conventional space time block coded MIMO systems. |
