摘要： A method and apparatus for channel estimation in a rake receiver of a CDMA communication system operates with a finite-impulse-response channel estimation filter with L taps and having a fixed delay. A pilot sequence of a received sequence of data from a channel of the communication system on the rake receiver is input. A quality of the channel of the communication system is determined using noise or Doppler measurements. These measurements are used in adjusting a bandwidth of the filter to accommodate the channel quality while keeping the fixed delay, which minimizes the delay buffer size. The filter is then used to operate on the received sequence of data to provide coherent modulation.

摘要： The present disclosure includes a discussion of a decision-directed clock recovery system which includes circuitry to prevent false-locking and accelerate acquisition on a known symbol patterns. The clock recovery system has at least two control circuits. Each control circuit has an effective bandwidth and also generates a clock signal. The clock recovery system samples the received data signal using the two clock signals, forming a corresponding first and second sampled signal. The sampled signals are used to generate corresponding symbol decisions. The symbol decision signals are processed to detect a known symbol pattern in the received data signal. Upon detection of the known bit sequence, the characteristics of the clock recovery system are modified, namely, the effective bandwidth of the control circuits are modified.

摘要： The present patent application discusses a frequency translation apparatus for altering the effective frequency of the phase information of an input signal (115). The input signal (115) has a first phase (.theta.(t)) and a first frequency (f.sub.i). The phase of the input signal is extracted and digitized at a second frequency (f.sub.o), forming a second N-bit digital phase signal (.theta.'(t))(311). The frequency translation apparatus generates a third digital phase signal (319) which approximates the difference between .theta.(t) and .theta.'(t). Then, the frequency translation apparatus combines the second digital phase signal and the third digital phase signal, forming a fourth digital phase signal (307) substantially approximating the first phase signal.

摘要： A method of and apparatus for compensating a received signal's phase compensates for the distortion caused by the asymmetrical characteristics of a voltage limiter. This compensation allows the received signal to be sampled at the positive and negative zero-crossings reducing the requirements of a local oscillator in a radiotelephone system. First, the phase of the received signal is sampled at the positive and negative zero-crossings, forming a corresponding positive-crossing and a negative-crossing phase value for the received signal. Second, the negative-crossing and positive-crossing phase values are combined, forming a first difference signal. Third, an estimated error signal is formed using the first difference signal. Fourth, the estimated error signal is combined with the positive or negative zero-crossing phase signals, substantially eliminating the asymmetrical distortion.

摘要： A radio receiver directly digitizes the phase of an intermediate frequency (IF) signal with a desired resolution. The frequency of the reference oscillator in the direct phase digitizer is reduced when compared to the frequency previously required for the same resolution. The reduction in the reference oscillator frequency is accomplished by differentiating between IF zero-crossings that occur during the first half of a reference oscillator cycle and zero-crossings which occur during the second half of the reference oscillator cycle. The apparatus utilizes 2 zero-crossing detectors, the first zero-crossing detector is driven by a positive edge of the reference oscillator signal and the second zero-crossing detector is driven by a negative edge of the reference oscillator signal. Depending upon the alignment of the negative edge zero-crossing indicator and the positive edge zero-crossing indicator, the N-bit phase signal is modified or shifted by one-half a phase sector.
