Abstract: The present invention relates to a system and method for extending the coverage area and communication capacity of a spread-spectrum based wireless network. The system comprises a unique dual-scale, asymmetrical cellular architecture for a wireless network, wherein the communication uplink is based on a macro-cellular system, and the communication downlink is based on a micro-cellular system. Through the user of remote downlink transmitters in the micro-cellular system, the present invention provides a cost effective solution for increasing communication capacity and extending coverage area.

Abstract: The present invention relates to a system (100) and method for extending the coverage area and communication capacity of a spread spectrum based wireless network through the use of intelligent repeaters (130). The system (100) comprises a wireless communications network augmented with low cost channel selective repeaters (130) that is capable of repeating only desired signals, thereby suppressing undesirable interference and increasing network capacity. The repeaters (130) can be integrated into an existing wireless network with minimal impact to the existing network topology or control structure.

Abstract: Reducing multiple access interference in the radio frequency communications path between the network base station and UE. The preferred methods include interleaving STAP and MUD in a plurality of stages in a base station receiver (100). Specific embodiments accomplish this by selecting certain UE connections for MUD processing by stage. Then, in two or more stages, demodulating the UE connections selected for MUD processing. Within the latency requirements of the network, preferred embodiments of the present invention also command a transmit power for each UE connection in order to exploit the effect of interleaved STAP and MUD processing.
