For routing a data unit through a chain of nodes, the nodes are assigned addresses that are increasing in one direction of appearance of the nodes in the chain. For routing the data unit, the receiving node first verifies if the destination address of the data unit corresponds with the address of its first hop neighbor or its second hop neighbor, and the node routes the data unit directly to its first hop neighbor or its second hop neighbor if this is the case. Otherwise, the node determines the difference between the destination address of the data unit and its own address or the difference between the source and destination address of the data unit, selects a routing direction depending on the sign of this difference, and selects a first hop link when the difference is in magnitude below a threshold value or a second hop link when the difference is above the threshold value.

Method and computer program products for routing a data unit

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.

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.
