OFDM SYSTEM AND METHOD EMPLOYING OFDM SYMBOLS WITH KNOWN OR INFORMATION-CONTAINING PREFIXES

摘要

Systems and methods for transmitting and receiving OFDM symbols are provided which enable the otherwise wasted transmission time normally used as a prefix for each OFDM symbol to contain useful information. At the receiver, the received signal is processed to convert received OFDM symbols from a linear convolution with the channel to a cyclic convolution.
