Abstract: A system and method are provided for implementing a peak-to-average power ratio (PAPR) reduction scheme for Orthogonal Frequency-Division Multiple Access (OFDMA) modulation. A unique PAPR reduction scheme for OFDMA modulation for systems operated according to a DOCSIS standard achieves results similar to those attributable to tone reservation schemes in a manner that does not negatively affect an amount of available data capacity, particularly in implementations with limited numbers of subcarriers. The disclosed systems and methods are particularly adaptable to next generation cable gateways and/or next generation cable modems. These next generation cable gateways and/or cable modems may find particular utility in advanced hybrid fiber/coaxial cable systems. The adaptable cable gateways/modems may include a cable gateway system-on-chip (SOC) configuration. The disclosed schemes may be applicable to OFDM modulation. For OFDM, however, the known tone reservation algorithms also may be employed.

Abstract: A direct conversion television receiver may include a phase de-rotator which substantially undoes the phase rotation of a phase rotator. The phase de-rotator takes the low pass filtered signal and substantially removes the rotation caused by the phase rotator. As a result, it is easier to estimate the phase and gain imbalance and to make a correction for the phase and gain imbalance, via a feedback loop, without the effects of phase rotation.
