US Patent 7778316 Detecting channel impulse magnitude response in digital communication systems

A system and method of detecting the location and magnitude of multi-path echoes in a channel impulse response by going through the channel impulse magnitude response only once and detecting all the multi-path echoes, both location and magnitude, according to certain threshold criteria. The impulse magnitude response samples are processed on-the-fly (on demand) and do not require the storage of the entire channel impulse magnitude response which makes it ideal for ASIC implementation.
