Abstract
Two transmit two receive space-time processingwith LDPC coding is evaluated for OFDM transmission.The two methodsfor space-time processing are Alamouti's combining and the SVD technique.The channel estimates are calculated and provided tothe diversity combiner, the SVD filters and LDPC decoder.Noise variance estimates areprovided to the LDPC decoder. Using the proposed schemewe can obtain a BER of 10−5 at an SNR of 2.6 dB withspectral efficiency of0.4 bits/sec/Hz and 14.5 dB with a spectral efficiency of 4.2 bits/sec/Hz.
