Abstract :
This paper investigates a transceiver design and analysis of DS-CDMA Ultra-wideband radio, which is adapted from an 802.15.3a OWE draft proposal for WPAN. The system uses M-ary bi-orthogonal keying modulation with ternary spreading code. The 802.15.3a Saleh-Valenzuela CMI-CM4 channel models are specified for performance evaluation. For channel dispersion over many consecutive symbols, we use not only rake receiver to compensate the inter-chip interference, but also decision feedback equalizer to eliminate the post-cursor inter-symbol interference. Moreover, using the Gaussian approximation technique, analytic upper-bound error performance is derived for the rake-only and rake-DFE receiver. The result is well matched to the simulation result. It also shows that the Rake-DFE attains a significant performance gain as compared to the rake-only receiver.
