Abstract
Pseudo random training symbols and/or a constant modulus pilot carrier in OFDM symbols are used to train an adaptive antenna array to cancel unwanted multipath signals and suppress interfering signals. Power variance and power level measurements taken from a plurality of antenna branches during the training symbols and/or the constant modulus pilot carrier are used to determine appropriate weights to be applied to each antenna branch.
