Method and device for determining an integer carrier frequency deviation in an OFDM system by evaluating different modulation values of various sub-carrier groups

摘要

The method involves potentizing each received Orthogonal frequency-division multiplexing symbol with an appropriate factor (I) of number of phase condition of the phase modulation. An average value is determined for the respective sub channel by potentizing the received orthogonal frequency-division multiplexing symbols in the respective sub channel. The proper factor is identified as integral multiple of the sub carrier interval in the carrier frequency deviation for maximum the determined metrics. An independent claim is also included for a device for determining a carrier frequency deviation.
