Multicarrier modulation has been gaining in popularity in recent years. It has been implemented in systems such as Digital Subscriber Loops, broadcast High Definition Television in Europe, wireless local area network standards such as IEEE 802.11a, power line communications, and satellite radio. In a multicarrier receiver, a time-domain equalizer (TEQ) is needed to mitigate the distortion due to the transmission channel. This typically takes the form of a filter that is designed such that the delay spread of the channel-TEQ combination has a much shorter delay spread than that of the channel alone.
This thesis has two thrusts: the primary goal is to propose, analyze, and simulate several blind, adaptive algorithms for designing the TEQ. The secondary goal is characterization and complexity reduction of both adaptive and non-adaptive TEQ designs. This will include examining symmetry of the impulse response and the locations of its zeros, as well as techniques to reuse calculations in laborious matrix computations.
