Patent ID: 7469003

Claim:
In a communication device receiving a spread spectrum signal which includes a common pilot channel (CPICH) signal and a plurality of dedicated physical data channel (DPDCH) signals, a method for performing channel equalization at a receiver, comprising: demodulating said plurality of DPDCH signals included in said spread spectrum signal; obtaining decisions for information symbols of said DPDCH signals included in said spread spectrum signal; re-spreading with a spreading code said decisions for information symbols of said DPDCH signals to regenerate said plurality of DPDCH signals; adding said regenerated plurality of DPDCH signals to the CPICH signal to produce a summed signal; re-scrambling said summed signal with a PN code to obtain an estimate signal of the transmitted spread spectrum signal received at the communication device; using said estimate signal to perform adaptive equalization; demodulating a voice signal included in said spread spectrum signal; obtaining decisions for information symbols of said voice signal included in said spread spectrum signal; re-spreading with a spreading code said decisions for information symbols of said voice signal to regenerate said voice signal; scaling said regenerated voice signal by a smaller value than a value used to scale a regenerated DPDCH signal; and adding said scaled voice signal, said regenerated plurality of DPDCH signals and said CPICH signal to produce said summed signal.
