Abstract:
The performance of carrier frequency offset (CFO) estimators is examined when applied to Hiperlan2 modems. The performance of various estimator procedures is evaluated by means of simulation. A new estimation scheme is proposed for Hiperlan2 that takes advantage of the structure of the physical frames. Its major advantage is that the estimator operating range is extended to fulfil a worst-case scenario of CFO for Hiperlan2. A CFO correction architecture is also proposed which consists of 2 parts; a coarse CFO estimator that feeds a numerically controlled oscillator (NCO) to remove a part of CFO, and a fine CFO estimator-corrector that uses linear phase extrapolation to correct the phase shift caused by the remaining CFO.
