Abstract: A code division multiple access (CDMA) receiver detects, de-scrambles, and de-spreads multiple channels that utilize different binary codes. The processing that is common to all channels can be performed once thus saving gate count and power consumption.

Abstract: A code division multiple access (CDMA) receiver can detect the presence of a GSM tone-based signal by programming the digital filter's tap weights to correlate with a GSM FCCH signal. If the correlation between the values of the tap weights and a received signal satisfies a threshold, the receiver produces an indication that a GSM signal is present. Post-processing can be performed on the output of the digital filter to improve signal detection based on the determination of the correlation of the received signal with the digital filter, the determination of the corresponding power value, the determination of the signal strength; and the estimation of the frequency offset.

Abstract: A golf ball includes a core and a cover layer. The core is formed of a first composition and the cover is formed of a second composition. The specific gravity values of each of the first and second compositions are generally equal to each other. The first and second compositions are each sufficiently mixed such that the ball exhibits random orientation when floated in a solution of sufficient density to support the ball. The weight, size, spherical symmetry, initial velocity and overall distance of the ball conform to the requirements of the United States Golf Association.
