Title:
ADAPTIVE COMMUNICATIONS METHODS FOR MULTIPLE USER PACKET RADIO WIRELESS NETWORKS
Document Type and Number:
WIPO Patent Application WO2002071770
Kind Code:
A9
Abstract:
An wireless communication network that includes a base that communicates with remote units (RU) located in a cell of the network. A base concatenates information symbols with a preamble corresponding to a destination remote unit. One or more remote units communicating with a base unit concatenates information symbols with a preamble corresponding to that RU. An adaptive receiver system for a base unit rapidly adapts optimal despreading weights for reproducing information symbols transmitted from multiple RU's. A transmitter system for a base unit concatenates information symbols with a preamble associated with a RU adapts optimal weights for reproducing a signal transmitted to it by a specific base unit in the network. A transmitter system for a RU in a cell of a communication network which concatenates information symbols with preamble associated with the RU.
