Abstract:
|
We analytically derive the upper bound for the bit error rate (BER) performance of a single user multiple input multiple output
code division multiple access (MIMO-CDMA) system employing parity-bit-selected spreading in slowly varying, flat Rayleigh
fading. The analysis is done for spatially uncorrelated links. The analysis presented demonstrates that parity-bit-selected spreading
provides an asymptotic gain of 10 log(Nt) dB over conventional MIMO-CDMA when the receiver has perfect channel estimates.
This analytical result concurs with previous works where the (BER) is determined by simulation methods and provides insight
into why the different techniques provide improvement over conventional MIMO-CDMA systems. |
