At the transmission time n, a binary data block b is modulated and then passed through the serial-to- parallel converter and a complex data matrix S with a length K×N is obtained, where N is the total number of OFDM symbols and K is the total number of subcarriers	cache/alkej-37.pdf	txt/alkej-37.txt
