| Abstract: Orthogonal Frequency Division Multiplexing (OFDM) technology is a key technique for achieving the high data rate and spectral efficiency requirements for wireless communication systems of the near future. UWB - Multiband OFDM has an acceptable BER performance. In a multipath noisy channel the bit error is very high. In this Paper we present the Barker code as a coding technique and solution to increase the BER performance using the correlation detection. The system performance is increased up to 11 dB for autocorrelation detection. The drawbacks of the system are the additional required bandwidth, congestion of the channel and the unexpected error position in the Barker sequence. In order to minimize bandwidth, Time-Frequency-Time using Direct and reversed Fourier transforms is used based on acoustic electronic processors. | ||||
