Auto-configuration of spectrum use by wireless pre-planned or ad hoc networks

A method of, and a wireless device capable of, dynamically allocating radio spectrum access within a wireless communication system includes a wireless transceiver having at least a physical layer functionality to transmit and receive data across a wireless network. The device extracts measurements of radio spectrum conditions from a least one of a local and a remote wireless transceiver to form an assessment of radio spectrum conditions. The device then integrates the assessment of radio spectrum conditions to form an integrated assessment of radio spectrum conditions between the local and remote wireless transceivers. The device further possesses a means for selecting a preferred set of radio spectrum access parameters for a communications session between the local and remote wireless transceiver.

Spreading code derived from weil sequences

Methods and systems relating to Weil-based spreading codes are described herein. In an embodiment, a method includes generating a set of Weil sequences, adapting a plurality of sequences of the set of Weil sequences to form a first plurality of codes, and selecting a second plurality of codes from the first plurality of codes. A code of the first plurality of codes is selected based at least on a correlation associated with the code. Each code of the first plurality of codes has a predetermined length.

System and method for interference cancellation with multi-stage multi-user detection

Reduction of multiple access interference, in one example for asynchronous CDMA systems using long codes. In one aspect, parallel interference cancellation (PIC) implements a decoupled estimate, preferably non-linear and applied at chip intervals. According to another aspect, interference is cancelled using a technique that estimates bits for a symbol by interpolating signature waveforms for users to a common sampling lattice of the received data. According to another aspect, multi-stage, hybrid multi-stage, and reconfigurable recursive multi-stage multi-user detection architectures and corresponding processes are provided.
