Multipath Effects in High Speed Digital Radio Communications.

The performance of high-speed wireless radio communication channels depends on the topology of the link. It is customary to define the performance in terms of the delay spread that can be tolerated. The multipath destroys the received signal in the receiver. This increases the errors in the demodulator. However, as we show in this tech brief, a parallel transmission on orthogonal coded basis can be use on the same channel to increase the signal to noise ratio and to reduce the errors especially on high speed data transmission. The paper presents an investigation of the errors due to some known channel models of the traditional transmission. Also we present simulation of the same channel speed using orthogonal frequency division multiplexing. The results for the orthogonality and the errors in the demodulator are published on the conclusion of the paper. [ABSTRACT FROM AUTHOR]
