Abstract
Embodiments for a method and apparatus are described for non-linear noise cancelation and in phase quadrature (I/Q) modulation error correction. The embodiments include receiving a signal, the signal including a plurality of data segments. A first data segment in the received signal is demodulated and decoded to produce a recovered segment of a bitstream. At least one correction factor is applied to a first demodulation support element and a second demodulation support element during demodulation of a second data segment in the received signal. The correction factor is determined based on the received first data segment and a representation of the first data segment reconstructed from the recovered segment of the bitstream.
