  • Publication number: 20140134943
    Abstract: A system and method of monitoring a signal repeating device in a wireless communication system is provided. An operational noise measurement is obtained by measuring a noise value outside of a bandwidth of a first element, but within a bandwidth of a second, subsequent element in a signal path of the device. The operational noise measurement is alternatively obtained by tuning an input band of the device to shift the input band partially or completely outside of a bandwidth of a first element to create an open band or by suppressing an input of an antenna and measuring noise within the open bandwidth of the device. A stored parameter is retrieved and compared to the measured operational noise. Alternatively, a leakage signal of the device may be received at a signal receiver and compared to a reference. The reference is a function of elements of the device in a leakage path of the leakage signal.

  • Publication number: 20140119281
    Abstract: A telecommunications system is provided that includes a unit for communicating channelized digital baseband signals with remotely located units. The channelized digital baseband signals include call information for wireless communication. The unit includes a channelizer section and a transport section. The channelizer section can extract, per channel, the channelized digital baseband signals using channel filters and digital down-converters. The transport section can format the channelized digital baseband signals for transport together using a transport schedule unit for packetizing and packet scheduling the channelized digital baseband signals. A signal processing subsystem can control a gain of uplink digital baseband signals, independently, that are received from the remotely located units prior to summing the uplink digital baseband signals.

  • Patent number: 8711976
    Abstract: An input signal is pre-distorted to reduce distortion resulting from subsequent signal amplification. Frequency-dependent pre-distortion is preferably implemented in combination with frequency-independent pre-distortion, where the frequency-dependent pre-distortion is generated by expanding the derivative of a product of a pre-distortion function and the input signal and then relaxing constraints on the pre-distortion function and/or on frequency-dependent filtering associated with the frequency-dependent pre-distortion. In one implementation, four different frequency-dependent pre-distortion signals are generated for the expansion using up to four different pre-distortion functions and up to four different frequency-dependent filters.
