Multi Band OFDM System Model and Its Performance Evaluation for UWB Communication

In this work multiband orthogonal frequency division multiplexing (OFDM) System is modeled and its performance evaluation is analyzed for ultra wide band (UWB) communication environment. Theoretical derivation for the average pairwise error probability (PEP) and Outage Probability are derived based on Saleh and Valenzuela fading model. In line with this, the impact of joint coding the information across subcarriers in the system performance is investigated. The link budget analysis is also computed and results are obtained in regard to the transmission range for indoor environments. Moreover, average coded bit error rate achieved from convolutional codes over the system is computed and supported with computer simulations for all UWB channel conditions.
