5.4. Channel Impulse Response Model

We have examined the general transmission characteristics of indoor radio frequency channels in terms of signal losses. To utilize the transmission potential of the channel fully, an optimized transceiver architecture is required. The choice and design of the transceiver architecture including signal modulation and detection methods depend on the impulse response and the noise environment of the channel. The impulse response of an indoor radio frequency channel is useful at determining how fast the signaling rate could be with or without using certain types of channel equalization techniques. The channel impulse response can be exactly calculated if the reflection mechanism is relatively simple. Such a simple ...
