Abstract: A Wireless Code Division Multiple Access method and apparatus for determinin g the transmitted rate of a voice/data signal from a mobile station to a Base Station. Variable rate vocoders transmit voice at one of several predetermin ed frame rates. The receiver determines the transmitted rate based on one of several frame parameters. One of the parameters is received frame energy. Th e received frame energy is measured over the length of the relevant portion of the frame. Energy is measured over the half of the frame that can only conta in energy if a full rate frame is sent. If the energy measured exceeds a threshold, then full rate is indicated. Else, energy is measured over the fourth of a frame that can only contain energy if a half rate frame is sent. If the energy exceeds a threshold, then half rate is indicated. The procedur e is repeated for quarter and eighth rates.

Abstract: A wireless receiver receiving multipath Walsh-code symbols determines which of fingers (402, 410) have locked on a signal. Measurements of the correlation energies between the received signal and all possible symbols are stored in energy storage units (404, 412). The actual signals are combined in combiner (408). A maximum determiner (416) determines the most likely combined symbol , and an index for this symbol is fed back to the energy storage units. Lock detectors (406, 414) use the measurement for this fed-back symbol to determi ne whether the finger has locked onto a path. This determination is used to decide whether the next signal detected by that finger should be applied to the combiner.

Abstract: A method and apparatus for compressing fixed point signals without introduci ng a bias. Signals are compressed according to a dithered rounding approach wherein signal values are rounded up and rounded down with approximately equ al probability, canceling the bias that would otherwise result from the roundin g operation. Numerical properties of the input signal are exploited in order t o determine whether the signal value should be rounded up or down. Signal compression may, therefore, be introduced at multiple points within a system without accumulating a signal bias and degrading downstream performance. Further, one bit signal compression may be achieved in a particularly efficient fashion with a minimal amount of hardware.

Abstract: Techniques for detecting acquisition of a false channel in a wireless communication system are described. For false channel detection, a peak corresponding to a signal from a base station is initially detected. Frequency acquisition and time tracking of the peak are then performed. The frequency acquisition attempts to determine and correct downconversion frequency error. The time tracking attempts to follow the peak as it moves due to sample timing error and/or changes in channel conditions. Whether the signal is from a desired frequency channel or a false frequency channel is determined based on the time tracking. If a false channel is acquired, then the sampling timing will be either too slow or too fast, and the peak will move at a fast rate. A false channel may be detected based on the movement of the peak.
