Patent ID: 8848814

Claim:
A mobile terminal for receiving a signal transmitted over a communication channel, wherein the signal carries symbols that have been multiplexed on orthogonal frequency sub-carriers, the mobile terminal comprising: channel estimation logic configured to estimate a pulse response for the communication channel, wherein the pulse response is estimated from predetermined information contained in the received signal; transform logic, wherein, for each symbol, the transform logic is configured: to perform a transform on a first window of time domain samples of the received signal to obtain a first set of frequency domain samples; to perform a transform on a second window of time domain samples of the received signal to obtain a second set of frequency domain samples, wherein time positions of the first window and second window are determined based on an analysis of energy peaks occurring in the pulse response; and symbol estimation logic, wherein, for each symbol, the symbol estimation logic is configured to estimate the symbol from data including the first and second sets of frequency domain samples.
