Rayleigh ber at high snr
WebMulticarrier Code Division Multiple Access (MC-CDMA) is an attractive technique for high speed wireless data transmission in view of its advantages over orthogonal frequency division multiplexing. In WebMultiple-Input Multiple-Output (MIMO) wireless antenna systems have been recognized as a key technology for future wireless communications. The performance of MIMO system can be improved by using multiple antennas at transmitting and receiving side to provide spatial diversity. In this paper, the effects of the number of transmit and receive antennas on the …

Web(BER). The resulting expressions are general, as they hold for an arbitrary number of reflecting elements N, and quantization levels, L. We introduce an exact asymptotic analysis in the high signal-to-noise ratio (SNR) regime, from which we demonstrate, in particular, that the diversity order is N/2 when L = 2 and N when L > 2. summersville post office hoursWebthe level of background noise. The higher the ratio, the less obtrusive the background noise is. SNR = (Psignal / Pnoise) = (Asignal / Anoise) 2 While considering effect of BER on SNR, results shows that the BER performance is improved dramatically in low SNR, while not in high SNR.
