An efficient framework to exploit frequency diversity in OFDM: precoding with adaptive subcarrier selection
We propose adaptive subcarrier selection (ACS) as an efficient technique of improving the error performance of grouped linear constellation precoding (GLCP) OFDM in the low-to-medium SNR range (0-20 dB). Recently, GLCP-OFDM has been proposed to achieve frequency diversity (multipath diversity) in OFDM overcoming the problem of channel nulls (deep fades in frequency-domain). In GLCP-OFDM, symbol precoding is performed on subgroups of OFDM subcarriers rather than on the total number of OFDM...[Show more]
