Abstract
A receiver for implementing a training prefix modulation method in response to a reception of a signal propagating through a channel is disclosed. The signal as received includes training blocks with each training block having a data inter-block-interference therein, and data blocks with each data block having a training inter-block-interference therein. The signal is selectively reconstructed to provide a circular appearance of the channel over the data blocks. Specifically, an estimate of the training inter-block-interferences is generated and subtracted from the data blocks. And, an estimate of the data inter-block interferences is generated and added to the data blocks.
