OFDM符号的类型判断与1_2保护间隔预校正-OFDM symbols to determine the type of 1_2 guard interval with pre-correction

OFDM系统的保护间隔的BER特性 保护间隔为16-BER performance of OFDM systems the guard interval guard interval is 16

Function to insert guard interval into transmission signal.Function to remove guard interval from received signal

basic concept of OFDM is quite simple [4]–[7]. Data is transmitted in parallel on a number of different frequencies, and as a result the symbol period is much longer than for a serial system with the same total data rate. Because the symbol perio
