    Abstract: Techniques for generating quality indicator bits in a wireless communication system (e.g., a cdma2000 that implements IS-2000). In one method, a determination is first made whether a good data frame was received from a first transmission for the current frame interval. This first transmission may be a non-continuous transmission on a forward dedicated control channel (F-DCCH) defined by IS-2000. If a good data frame was received, then a quality indicator bit is generated based on the good data frame. Otherwise, the quality indicator bit is generated based on a second transmission, which may comprise power control bits that are transmitted even when no data frames are sent in the first transmission. The received signal quality for the power control bits can be measured and compared against a threshold, and the quality indicator bit is then set based on the result of the comparison. The threshold may be dynamically updated.

    Abstract: Noise gain control within a communications receiver allows optimization of the receiver design without regard to the predetermined Automatic Gain Control set point. A noise gain controller is provided a copy of the received signal following AGC stages. A noise estimator determines the level of noise within the received signal and couples the noise level estimate to a noise gain discriminator that processes the noise level estimate to produce a gain correction factor. The gain correction factor is filtered and accumulated. The accumulated gain correction factor is used to scale the received signal. Subsequent receiver stages process the scaled received signal.

    Abstract: The punctured pilot channel comprises information symbols of uncertain sign punctured into a sequence of pilot channel symbols of predetermined sign. The apparatus includes an information sign demodulation circuit for determining the sign of the information symbols in response to the pilot channel symbols. A continuous pilot generator generates a non-punctured pilot channel of predetermined sign from the information symbols and the pilot channel symbols. In a first embodiment, the information sign demodulator further comprises a dot product circuit for calculating a dot product of the pilot channel symbols and the punctured information symbols, and a threshold comparator for comparing the dot product to a predetermined threshold.

    Abstract: A forward link repeater delay watermarking (FLRDWM) system and method that enable accurate position location of mobile stations in areas where repeaters are present by watermarking repeated signals with repeater information. A repeater watermarks a forward link signal with a (unique or non-unique) time delay modulation waveform watermark every time a signal passes through the repeater. A mobile station detects and/or identifies the time delay watermark on the forward link signal to determine repeater information that aids the network position determination entity or mobile station position location system in determining position location using AFLT and/or A-GPS systems. A forward link time delay watermarking system can be implemented to achieve low impact on FL and AFLT performance, favorable detection and identification probabilities, and short time-to-detect/identify.

    Abstract: Systems and techniques are disclosed relating to communications. The systems and techniques involve spread-spectrum communications using a scheduler, or similar component, configured to maintain a plurality of spreading sequence assignments and a plurality of available spreading sequences each being orthogonal to the assigned spreading sequences. The scheduler may also be configured to select a spreading sequence from a group of the available spreading sequences having the same length, the selected spreading sequence being generated from a block of codes and being selected based on the number of the available spreading sequences that can be generated using the same block of codes.
