Paper Abstract

In this work we compare an orthogonal frequency division multiplexing (OFDM) single user through multi carrier system with Direct Sequence Spread Spectrum (DS- SS) in the presence of multipath fading and AWGN. A closed-form of mathematical expressions for both receivers is derived to calculate the symbol error probability. The OFDM system simulator is an IEEE 802.15.3a proposal, dated 15 September 2003 (Doc: IEEE P802.15-03/268r1). Conventional matched filter (MF) is proposed in DS-SS system. UWB - Multiband OFDM has an acceptable BER performance, but in a multipath noisy channel the bit error rate is very high. This Paper presents the Barker code as a coding technique to increase the BER performance depending on the auto and cross correlation detections.
