Abstract

A multiple step process is performed at a local wireless network to limit interference between the local wireless network and a remote wireless network. Initially, a set of code words is chosen for the local wireless network to encode data with that have good cross correlation properties. If these initial code words are not adequate to prevent interference, then the local wireless network will adjust its transmission parameters by either shifting the transmission phase of its signals or by changing the code words it uses. If altering the transmission parameters does not alleviate the interference problem, then the local wireless network attempts to locate the interfering remote network (1825) and merge with it (1865). If the merger is not possible or is unsuccessful, then the interference limiting process fails (1820).
