In one embodiment, a TFI-OFDM receiver system (22) is able to more reliably decode the information bits by estimating the noise variance associated with the channel and using these estimates in mitigating in-band interference. In another embodiment, there is a TFI-OFDM receiver system (66) that is able to update the estimated channel impulse response and the noise variance by generating reference OFDM symbols from the received header symbols, the band hopping pattern provided by the TFC number associated with the communication link, the estimated channel impulse response and the noise variance estimates and symbols generated from a FFT processor (30). |
