Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely:  address the problem of non-data aided frequency offset estimation for non-circular transmissions over frequency-selective channels in a downlink DS-CDMA system or an OFDM communications context.  observe that twice the frequency offset is a cyclic frequency of the received signal.  thus introduce an estimator relying on the maximisation of the empirical cyclocorrelations.  analyse its asymptotic behaviour and obtain a closed-form expression for the asymptotic covariance. This enables us to design relevant system parameters. Simulations are provided and confirm our assertions.
