Abstract: Systems and methodologies are described that facilitate dynamically allocating demodulation resources of a wideband receiver to provide improved demodulation of simultaneously received signals. Signal-to-noise ratio (SNR) and/or packet error rate (PER) can be measured for the plurality of carriers to determine which demodulators related to the carriers require more resources than others to demodulate signals at a specified signal quality. Where the SNR of a related carrier is high and/or PER is low, the demodulator can require fewer resources than where the SNR of a related carrier is low and/or PER is high. In this regard, the resources are dynamically allocated among the demodulators and reallocated where SNR/PER changes and/or additional resources are made available.

Abstract: A matched filter requiring no high-speed processor and which consumes less power is disclosed. Partial filters 301 - 30N obtained by dividing number of matched filter taps by N are provided with a controller 341 for controlling which partial filters are enabled. The controller 341 is supplied with maximum amount of delay of an input signal and with symbol timing. On the basis of the maximum amount of delay, the controller 341 enables only the minimum number of partial filters 301 - 30n that are capable of executing an amount of computation that is required in one symbol period. The enabled partial filters are used multiple number of times per symbol period and the output, each time, integrated sample by sample. Since the disabled partial filters will not operate, it is possible to reduce power consumption and computation time.

Abstract: A wireless telecommunications system (1) includes a central terminal (10) for transmitting and receiving radio frequency signals to and from a subscriber terminal (20). A downlink communication path is established from a transmitter (200) of the central terminal (10) to a receiver (202) of the subscriber terminal (20). A downlink signal (212) is transmitted from the transmitter (200) to the receiver (202) during setup and operation of the wireless telecommunications system (1). The wireless telecommunications system (1) operates in one of three operating modes. In an acquisition mode during establishment of the downlink communication path, the downlink signal (212) is transmitted at a high power level and a low transmit rate with the receiver (202) operating at the low transmit rate. In a standby mode after establishment of the downlink communication path, the downlink signal (212) is transmitted at a low power level and a low transmit rate with the receiver (202) operating at the low transmit rate. In a traffic mode upon a request for wireless communication transmission, the downlink signal (212) is transmitted at a high power level and a high transmit rate with the receiver (202) adjusting to operate at the high transmit rate. Upon completion of the wireless communication transmission, the wireless telecommunications system (1) returns to the standby mode and the receiver (202) adjusts to operate at the low transmit rate.

Abstract: A central terminal (10) in a wireless telecommunications system (1) includes an analog card (206) that combines inputs from a plurality of modem units (204) for a plurality of downlink communication paths. The analog card (206) generates a composite transmit signal (214) that is provided to a radio frequency card (208). The radio frequency card (208) prepares the composite transmit signal (214) for radio frequency transmission from the central terminal (10). A power amplifier (218) in a combining shelf (201) amplifies the composite transmit signal (214) to a desired transmitting level. A detector (240) measures a power output of the power amplifier (218). The power output measurement determined by the detector (240) is collected by a combiner monitor (222) and delivered to a shelf controller (210) of the modem shelf (200). The shelf controller (210) provides the power output measurement to the analog card (206). The analog card (206) compares the power output measurement to power estimates of the inputs from the modem units (204). The analog card (206) generates an adjustment signal (242) to control the power output from the power amplifier (218) by adjusting a gain of the radio frequency card in accordance with the comparison.
