A communication device for W-CDMA signal transmission and reception has a W-CDMA transmitter having at least one of a first RAM and first registers, wherein the transmitter is configured to operate in accordance with first parameters. Further, the communication device has a W-CDMA receiver having at least one of a second RAM and second registers, wherein the receiver is configured to operate in accordance with second parameters, and signal acquisition component. A processor is in data communication with the W-CDMA transmitter, the W-CDMA receiver and the signal acquisition component, and configured to provide for software configuration of the first and second parameters.

Method and system for high-speed software reconfigurable code division multiple access communication

A communication device for W-CDMA signal transmission and reception includes a W-CDMA transmitter having at least one of a RAM and registers, a W-CDMA receiver having at least one of a RAM and registers, and a signal acquisition circuit. The communication device is software reconfigurable and further includes a digital circuit for phase unbalance precompensation in the W-CDMA transmitter. The digital circuit includes an input register holding a compensation angle and a section performing arithmetic calculations to acquire a change of an I, Q angle by the compensation angle. A method of operating a W-CDMA communication device includes the acts of configuring the device for a specific use, and performing at least one of transmitting, receiving and acquiring waveform signals. The configuring is preferably done by a processor.

Method and apparatus for high-speed software reconfigurable code division multiple access communication

A method for constructing orthogonal codes of length N for use in a network utilizing quasi-synchronous code division multiple access combined with time division duplexing. The method determines the balanced vectors of length N, being all possible cross-correlation vectors resulting from zero cross-correlation of codes of length N. An arbitrary code of length N is utilized, and a bitwise XOR-ing is performed with all the balanced vectors to produce a set of codes with which the arbitrary code is orthogonal. A bitwise XOR-ing of the original balanced vectors is performed and the code is added to a set of orthogonal codes if the result of the bitwise XOR-ing of the original balanced vectors is balanced. The method is repeated until the set of orthogonal codes is complete.

Method and system for code division multiple access communication with increased capacity through self-noise reduction

A method of generating a waveform with a plurality of orthogonal PN codes for use in a communications network utilizing quasi-synchronous code division multiple access. The orthogonal PN codes modulate multiple data streams together with a non-orthogonal PN code having desirable auto-correlation properties. The result is a complex signal with time-aligned PN codes.
