Good morning, i have a problem in the component OFMD modulator( by changing CP length) when i transmit a sequence bit (for example 16384 bits) in the reception i found some bits in last part of sequence equal zero , i think the problem in the time window when i increase the CP length ( in ofdm modulator) a part of sequence is out of window so in ofdm demodelator by removing CP i found zero in the of last part of sequence. please help me to solve this problem.
