COMBINING PILOT-SYMBOL-BASED PHASE ESTIMATION WITH DATA-SYMBOL-BASED PHASE ESTIMATION
First Claim
1. A method for a receiver to estimate phase of a carrier wave, comprising:
- receiving a carrier wave carrying pilot symbols and data symbols extending between the pilot symbols;
determining phase of the carrier wave at received pilot symbols; and
interpolating the phase of the carrier wave at points between pilot symbols based, at least in part, on an estimated phase of demodulated data symbols.

Abstract
A method for a receiver to estimate phase of a carrier wave, including receiving a carrier wave carrying pilot symbols and data symbols extending between the pilot symbols, determining phase of the carrier wave at received pilot symbols, and interpolating the phase of the carrier wave at points between pilot symbols based, at least in part, on an estimated phase of demodulated data symbols. Apparatus for estimate phase of a carrier wave, including a unit for determining phase of the carrier wave at received pilot symbols, and a unit for interpolating the phase of the carrier wave at points between pilot symbols based, at least in part, on an estimated phase of demodulated data symbols. Related apparatus and methods are also described.
