Abstract: A bit rate processor in a wireless system includes a front end processor to process physical channel data and to generate encoded transport channel data, a transport channel buffer to hold the encoded transport channel data, and a back end processor to process the encoded transport channel data from the transport channel buffer and to generate decoded transport channel bits. The front end process may include a frame buffer that receives the physical channel data, a first stage to de-map the physical channel data from the frame buffer, an intermediate frame buffer that receives the de-mapped physical channel data from the first stage, and a second stage to process the de-mapped physical channel data and to provide the encoded transport channel data. The back end processor may include a third stage, including a scaling circuit to scale the encoded transport channel data, a decoder to decode the scaled transport channel data and a CRC checker to provide the decoded transport channel bits, and an output buffer to receive the decoded transport channel bits.

Abstract: A system and method are provided for determining whether a chipping code from a group of codes is used in a signal. In one embodiment of the invention, a signal is received and each code from the group is correlated with the received signal. The ratio of the highest correlation value to the second highest correlation value is calculated. If the ratio exceeds a threshold, the chipping code may be determined as the chipping code used in the signal. In another embodiment, the ratio of the highest correlation value and the total received power of the signal is calculated. If the ratio exceeds a threshold, the chipping code may be determined as the chipping code used in the signal.
