Wireless Communication System Based Coded Ofdm Transceiver: Optimization of COFDM System With Reed-Solomon Code Using Radial Basis Function (RBF) Equalizer - Tapa blanda

Sinopsis

The design and implementation of capable constructing a new structure of RBF network equalizer based coded-OFDM. The importance of this design is to develop the conventional OFDM using channel estimator to compensate for the intersymbol interference (ISI) which suffers from multipath propagation and time varying channel, especially with mobile communication. The proposed structure solves the time-varying multipath signal propagation problem using equalization at the receiver. This requires and uses the channel coding to further protect transmitted data. Coded OFDM combined with channel equalization is considered the most effective means for a frequency selective fading channel. The research importance lies in using the radial basis function (RBF) network equalizer as a classification problem, where the idea is to map the received complex-valued signal into desired binary values. Results prove that the RBF network provides very good bit error rates with acceptable computational complexity.
