CHANNEL MODELS FOR INDOOR WIRELESS TRANSMISSION

In this paper a procedure is given for obtaining the channel impulse response for a rectangular room in terms of image sources. Exact image source strengths are evaluated using the Laplace transform formulation of the Sommerfeld problem. The coherent component of the impulse response is shown to exhibit significant variation is space. The performance of a decision feedback equalizer is examined in this context. The number of feed-forward and feedback taps required for a prescribed performance level is shown to be strongly influenced by the transmission frequency and source/receiver position.
