Abstract
A noise cancellation method comprises receiving, by an adaptive phase-noise cancellation apparatus, an incoming symbol from a receiver, performing a hard decision process on the incoming symbol to generate a corresponding clean symbol of the incoming symbol, generating a conjugate instance of the corresponding clean symbol, multiplying the orthogonal instance of the incoming symbol by the conjugate instance of the corresponding clean symbol to generate an intermediate component and calculating a phase deviation of the incoming symbol based upon a real part of the intermediate component and an imaginary part of the intermediate component.
