Abstract: An adaptive data slicer which functions to adapt to changes in the properties of a signal input thereto by producing a near optimal slicing threshold in accordance with the input signal for use in a decision circuit. The slicing level is considered optimal when its use in the decision circuit minimizes the bit error probability. The data slicer utilizes two peak detectors, a maximum peak detector for detecting the highest levels of the input signal and a minimum peak detector for detecting the lowest levels of the input signal.

Abstract: A novel frequency synthesizer incorporating a band switching VCO having a low KVCO tuning factor enabling operation with low supply voltage and low susceptibility to noise and frequency pulling. The VCO has a low tuning factor that covers only a small portion of the operating frequency range, depending on the number of bands into which the frequency range is divided. The normal phase locked loop operation of the synthesizer is preceded by an open loop band selection procedure which results in faster lock time and a lower required tuning voltage range for the VCO. The frequency band selection is made using frequency measurements. Alternatively, a band select LUT and channel LUT are generated a priori during a calibration stage in order to speed frequency acquisition and band selection.

Abstract: A GFSK modulator suitable for use in an RF communication system comprising a modular subsystem and a baseband processor subsystem which is implemented digitally. The baseband processor subsystem comprises a Gaussian filter, phase accumulator and cosine and sine look up tables. The baseband processor functions to convert an input data sequence into I and Q output signals. The I and Q signals are subsequently modulated by a quadrature modulator to yield a GFSK modulated signal which can then be amplified and placed into the channel. The response of the Gaussian filter is pre-calculated for all possible combinations of the input data and the results are quantized and stored in a look up table. The quantized phase results (either magnitude or differences), generated in response to the input data, are accumulated digitally and converted to I and Q signals.
