    Abstract: PROBLEM TO BE SOLVED: To provide an apparatus (100) and a method (400) suitable for use in a communication device by equalizing an input signal received to mitigate multipath distortion effects present in the input signal in the communication device.
    SOLUTION: A first filter (102) samples an input signal (104) and generates a first filter output (106) based upon the sampled input signal and a filter coefficient array (108). An error signal (112) is then generated based upon a difference between the first filter output (106) and a desired signal (114), and the filter coefficient array (108) is updated based upon a product of the error signal (112) and an adaptation constant (118). A second filter (126) samples a delayed input signal (124) and generates a second filter output (128) based upon the sampled delayed input signal and the filter coefficient array (108).

    Abstract: PROBLEM TO BE SOLVED: To provide a lake receiver and a finger managing method improved for providing the merit of path diversity even when the interval of multipath radio waves is shorter than one-chip time. SOLUTION: A lake receiver 112 is provided with plural fingers 122, 124 and 128. Each finger is provided with a demodulator for demodulating the radio waves of multiple path signals and a time tracking circuit for controlling the timewise position of the finger based on the timewise position of the radio wave. Low delay spreading conditions are detected, the positions of two adjacent fingers are controlled and fingers more than two are prevented from being converged around a common timewise position. By maintaining the timing intervals of fingers, even during low delay spreading conditions, the path diversity is effectively utilized by the lake receiver 112 and the performance of the receiver is improved.

    Abstract: A demodulator (414) for improving bit error rate performance consists of a zero threshold comparator circuit (502), a first threshold detector circuit (508), and a second threshold detector circuit (504). The first threshold detector circuit (508) compares the frequency information signal to a predetermined threshold, which is selected to optimize bit error rate performance. The second detector threshold circuit (504) is used to ensure that an alternating bit pattern has occurred. The demodulator (414) also includes a control device circuit (516) for coupling a plurality of bits (522) from a zero threshold comparator (502) to the output of the control device as a decision output signal (416) when the frequency information signal falls outside of either the first or second detector thresholds (508, 504). If the frequency information signal falls within both thresholds of the detector devices, then the decision output signal (416) for the control device (516) is formed by inverting the bit decision from the previous bit interval.

    Abstract: An apparatus (100) and a method (400) suitable for use in a communication device by equalizing an input signal received to mitigate multipath distortion effects present in the input signal in the communication device are provided. A first filter (102) samples the input signal (104) and generates a first filter output (106) based upon the sampled input signal and a filter coefficient array (108). An error signal (112) is then generated based upon a difference between the first filter output (106) and a desired signal (114), and the filter coefficient array (108) is updated based upon a product of the error signal (112) and an adaptation constant (118). A second filter (126) samples a delayed input signal (124) and generates a second filter output (128) based upon the sampled delayed input signal and the filter coefficient array (108). The duration of the delay (120) applied to the input signal or/and the adaptation "constant" may be varied based upon a rate of change of the input signal.

    Abstract: By time-sharing demodulator hardware between a primary data path (165), a power control data path (161), and a received signal strength indicator (RSSI) path (163), an entire power control data path (161) can be implemented in a demodulator (140) of a spread spectrum subscriber unit receiver with a low increase in gate count. The primary data path (165) and the power control data path (161) time-share a complex conjugate generator (270), a complex multiplier (280), and a real component extractor (290). Due to timing requirements, though, the channel estimation filter (240) of the primary data path cannot be time-shared with the power control data path. Instead, dynamic coefficient scaling is added to an infinite-duration impulse response (IIR) filter in the RSSI path (163) so that the IIR filter (250) with dynamic coefficient scaling can be time-shared between the RSSI path (163) and the power control data path (161).
