Abstract: A method is disclosed for obtaining a spreading code set for a code division multiple access (CDMA) communications system. The method includes (a) generating a P?×P? spreading code set where P?=P/N, where P is the spreading gain in chips/symbol and where N is an integer multiple of 2; and (b) replicating chips in each spreading code by N to produce a P?×P spreading code set. The step of generating may include randomizing the spreading code set by performing at least one or row or column permutation. The P?×P spreading code set is subsequently loaded into system hardware for operating the system hardware with a bandwidth that is less than the bandwidth that would be required to operate with the P?×P? Hadamard spreading code set. The CDMA system may be a synchronous, direct sequence code division multiple access communications system.

Abstract: Disclosed is a method, a computer system and a computer readable media product that contains a set of computer executable software instructions for directing the computer system to execute a process for determining a non-replicative behavior of a program that is suspected of containing an undesirable software entity. The process causes execution of the program in at least one known environment and automatically examines the at least one known environment to detect if a change has occurred in the environment as a result of the execution of the program. If a change is detected, the process automatically analyzes the detected change (i.e., the process performs a side effects analysis) to determine if the change resulted from execution of the program or from execution of the undesirable software entity. The process then uses the result of the analysis at least for undoing a detected change that results from execution of the undesirable software entity.

Abstract: Disclosed is a method for operating a code division multiple access communications system, and a system that operates in accordance with the method. The method operates within a coverage area of a base station by assigning a set of spreading codes to individual ones of a plurality of subscriber stations and then, during transmissions within the cell, by periodically hopping amongst spreading code within the set of spreading codes such that at any given time no two subscriber stations operate with the same spreading code. The set of spreading codes may include the all one's spreading code. The step of periodically hopping preferably changes from a currently used spreading code to a next spreading code at a symbol rate or at a multiple of the symbol rate.

Abstract: The present invention discloses a method of improving the coded speech quality in low bit rate analysis-by-synthesis (AbS) speech coders. This is accomplished by relaxing the waveform matching constraints for non-stationary plosive speech segments of speech signals by suitably shifting pulse locations of the coded excitation signal. The shifting results in the coded signal having phase information that does not exactly match original signal in places where it is perceptually insignificant to the listener. Furthermore, a technique for adaptive phase dispersion is introduced to the coded excitation signal to efficiently preserve important signal characteristics such as the energy spread of the original signal.
