Abstract:
A method for channel compensation in a multiple branch diversity receiving system, the method comprising the steps of:receiving a multiple-tone transmission signal on a plurality of antennas; and compensating for channel characteristic impacts on information signals on the multiple-tone transmission signal, wherein the step of compensating includes the following substeps in regard to the received signal from each of the plurality of antennas, detecting a symbol on a pilot tone selected from one of the multiple tones, generating first error estimation using the detected symbol on the pilot tone, generating a corrected symbol on others of said multiple tones using the received signal and the first error estimation, selecting a subset of said others of multiple tones as pseudo pilot tones, generating a second error estimation using said selected pseudo pilot tones, and generating an enhanced corrected symbol for said others of said multiple tones using the received signal and the second error estimation.
