Abstract: A Voice-Data-RF IC includes a baseband processing module, an RF section, and an interface module. The baseband processing module converts an outbound voice signal into an outbound voice symbol stream, converts an inbound voice symbol stream into an inbound voice signal, converts outbound data into an outbound data symbol stream, and converts an inbound data symbol stream into inbound data. The interface module provides selective coupling between the baseband processing module, the RF section, and with off-chip circuits.

Abstract: Hybrid multi-cell channel estimation. At least two different operational modes associated with performing multi-cell channel estimation are combined and performed within different respective iterations of processing in order to generate a multi-cell channel estimate. A device, including at least one wireless interface to support communications with at least one other device and also including at least one processor to process signals received by or to be transmitted from, is operative to generate a multi-cell channel estimate corresponding to two or more respective cells with which the device may communicate. A first operational mode corresponds to time domain (TDOM) based per-tap serial interference cancellation (SIC), and a second operational mode corresponds to frequency domain (FDOM) based per-cell SIC. One implementation operates with no more than one iteration of TDOM based per-tap SIC, and no more than two iterations of FDOM based per-cell SIC.
