    摘要: A radio frequency (RF) transmitter is coupled to and controlled by a processor to transmit data. A physical layer circuit is coupled to the RF transmitter to encode and decode between a digital signal and a modulated analog signal. The physical layer circuit comprises a high rate physical layer circuit (HRP) and a low rate physical layer circuit (LRP). In a first embodiment, the LRP circuit generates a LRP packet comprising an LRP transmit power control feedback. In a second embodiment, the LRP and HRP circuit generate a packet comprising a beam-forming phase and magnitude feedback information. In a third embodiment, the LRP and HRP circuit supports up to 64 independent transmit antenna elements.

    摘要: A pipelined cell search apparatus having a primary search stage, a secondary stage and a Gold code stage. The primary stage receives a primary synchronization channel (P-SCH) signal, detects a maximum peak of a slot boundary in the P-SCH signal, and generates slot timing data from the maximum peak. The secondary search stage receives a secondary synchronization channel (S-SCH) signal and the slot timing data, and detects in the S-SCH signal a maximum peak of a frame boundary. The secondary search stage generates frame timing data and a group ID of a base station transmitting the P-SCH signal and the S-SCH signal. The Gold code search stage receives a common control pilot channel (CPICH) signal, the slot timing data, the frame timing data, and the group ID and detects in the CPICH signal a maximum peak associated with a Gold code of the base station.
