摘要： Systems and methods which provide for reduced intra communication system information transfer by providing a compressed representation of a portion of intra communication system information are shown. An embodiment operates to provide intra communication system transfer of uncompressed received information while providing intra communication system transfer of a compressed representation of information ancillary to the received information. According to embodiments, ancillary information, such as CSI, associated with other transferred information is transferred with reduced data throughput requirements through application of compression techniques with respect to the transferred ancillary information. Embodiments additionally or alternatively reduce the intra communication system information transferred by reducing the received information transferred.

摘要： In one embodiment of the present invention, a dynamic multi-path detection device is disclosed to include at least one narrow-band signal metric estimator responsive to input signal. Each of the at least one estimators measures a particular characteristic of the input signal in a frequency band that is narrower than the overall signal bandwidth and is operative to generate a signal parameter estimate signal. The dynamic multi-path detection device is further disclosed to include a signal metric comparison device responsive to the signal parameter estimate signal(s) and operative to generate a dynamic multi-path indication signal for detecting dynamic multi-path.

摘要： A digital radio system comprises a mixer and an analog-to-digital converter communicative coupled to the mixer. The mixer generates an intermediate frequency signal based at least in part upon a radio frequency signal and a local oscillator signal, wherein the intermediate frequency signal comprises a signal of interest having a particular bandwidth. The analog-to-digital converter generates a digital signal by quantizing the intermediate frequency signal using a sampling frequency that is greater than twice the bandwidth of the signal of interest and less than the frequency of the intermediate frequency signal.
