  • Patent number: 10931241
    Abstract: An apparatus includes at least one processing device configured to obtain samples of an input signal to be amplified and, in real-time, pre-distort at least some of the samples using pre-distortion values from at least one lookup table. The pre-distorted samples are to be converted into an analog signal that is amplified by at least one power amplifier. The pre-distortion values at least partially compensate for a non-linear operation of the at least one power amplifier. The at least one processing device is also configured to compare an output signal generated by the at least one power amplifier to an expected signal to identify errors between the output and expected signals. The at least one processing device is further configured to update one or more pre-distortion values in the at least one lookup table based on the identified errors.

  • Patent number: 7936711
    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 through the use of intelligent repeaters. The system comprises a wireless communication network augmented with low cost channel selective repeaters that is capable of repeating only desired signals, thereby suppressing undesirable interference and increasing network capacity. The repeaters can be integrated into an existing wireless network with minimal impact to the existing network layer topology or control structure.

  • Patent number: 7630344
    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. 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 using STAP, and MUD canceling 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 connections in order to exploit the effect of interleaved STAP and MUD processing.

  • Patent number: 7535867
    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, extending coverage area, and providing high-speed communication downlink.
