摘要： In a communications device, two coherent detection algorithms (102 and 103), one of which has a decision feedback equalizer (103), and a detector selection algorithm (104) are used to dynamically select a detector depending on whether delay spread distortion is present. First the correlation of the detector without the equalizer (102) is measured. If this correlation is greater than a predetermined threshold, the data from that detector (102) is used by the communications device. If the correlation is less than the threshold, the correlation of the detector with the equalizer (103) is measured. If this is less than the correlation of the detector without the equalizer (102), the data from the detector without the equalizer (102) is used, otherwise the data is taken from the equalizer (103).

摘要： An automatic deviation control circuit for an angle modulated data transmitter is disclosed wherein the deviation level of modulated data is controlled by a modulation cancelling deviation error detection feedback loop. After the modulation is cancelled from a sample of modulated carrier by a predetermined value of deviation, residual modulation is detected, sampled following a predetermined number of like-level data bits, and applied to the modulation path gain to increase or decrease the deviation such that the residual modulation is minimized.

摘要： A clock recovery circuit for a digital TDM mobile radio transceiver is disclosed. In the "acquisition mode", a first phase-locked loop is configured to acquire synchronization with the input data signal, and a second phase-locked loop is coupled to the first PLL's output signal, thereby providing the recovered clock signal. The controller monitors the transmit control line and the received signal strength so as to switch the clock recovery circuit into a second configuration during a TDM transmit burst or a received signal fade. In this "hold mode", the second PLL is configured to free-run within a specified tolerance, while the first PLL is coupled to the second PLL's output signal. The controller maintains this "hold" configuration until the received signal is again present, and until the first PLL again acquires synchronization to the input data signal. In this manner, the controller prevents the recovered clock signal from losing bit synchronization or phase synchronization during transmit bursts, during the transmit-to-receive synthesizer out-of-lock period, or during Rayleigh fades. The present invention is particularly adapted for use in a TDM system utilizing 0.2 GMSK modulation, wherein there is less apparent clock signal available for clock recovery.

摘要： Improved method and apparatus in the form of coherent demodulators for MSK signal or other angle-modulated carrier signals of substantially constant amplitude and continuous phase are provided. The coherent demodulators include a frequency doubler, a first mixer for multiplying the frequency doubled signal with a half clock signal to produce a carrier term signal, a bandpass filter for filtering the carrier term signal and a divider coupled to the carrier bandpass filter to produce a coherent carrier signal. The half clock signal is generated by multiplying the frequency doubled signal with the filtered ouput signal of the carrier bandpass filter by a second mixer, and bandpass filtering the output signal of the second mixer to produce the half clock signal. The received binary data modulated signal and the generated coherent carrier signal are input to a quadrature detector for recovering the binary data.
