摘要： A spread-spectrum system and method for providing high capacity communications through multipath compensation. A multipath processor including a first plurality of correlators, a second plurality of correlators, a first adder, a second adder, and a selector device or a combiner device is provided for tracking a spread-spectrum signal arriving in a plurality of groups. The first plurality of correlators despreads a first group of spread-spectrum signals as a first group of despread signals which are added by the first adder to generate a first combined-despread signal. The second plurality of correlators despreads a second group of spread-spectrum signals as a second group of despread signals which are added by the second adder to generate a second combined-despread signal. The selector device selects either the first or the second combined-despread signal and outputs the selected signal. Alternatively, the combiner device combines the first and the second combined-despread signals and outputs the combined signal.

摘要： A variable bandwidth filter device for use with a spread-spectrum transmitter including a chipping sequence generator, a spread-spectrum processor, an impulse generator, and a filter. The chipping-seqence generator generates a chipping sequence signal having a chipping-sequence signal band-width. Using the chipping sequence signal, the spread-spectrum processor processes a data signal to generate a spread-data signal having a spread bandwidth greater than the chipping-seqence-signal bandwidth. In response to each chip in the spread-data signal, the impulse generator generates an impulse signal. The filter filters the spectrum of each impulse signal with a bandpass equal to the spread bandwidth. The invention also includes a method for generating a spread-spectrum signal using a chipping sequence having a rate less than the spread bandwidth. The method includes the steps of generating the chipping sequence, spread-spectrum processing a data signal with the chipping sequence, generating an impulse signal responsive to each chip, and filtering a spectrum of each impulse signal.

摘要： A method and apparatus for encoding and convolutionally decoding a data word of a data word sequence. For a data word having k bits, a 2.sup.k subset of signal points from a square set of M by M signal points having X coordinates and Y coordinates is selected using a trellis encoding algorithm and a previous data word. The square set of M by M signal points includes a constellation of 2.sup.k+1 signal points. A signal point from the selected subset of signal points is selected using the n.sup.th data word. A modulator generates a first FSK signal and a second FSK signal from the selected signal point. A demodulator demodulates the first FSK signal as a received X coordinate and the second FSK signal as a received Y coordinate. A 2.sup.k received subset of signal points is estimated by using the convolutionally decoding algorithm and a previously received data word. An n.sup.th received data word is estimated from the received X coordinate, the received Y coordinate, and the estimated-received subset of signal points.

摘要： A system and method of controlling transmission power during the establishment of a channel in a CDMA communication system utilize the transmission of a short code from a subscriber unit to a base station during initial power ramp-up. The short code is a sequence for detection by the base station which has a much shorter period than a conventional spreading code. The ramp-up starts from a power level that is guaranteed to be lower than the required power level for detection by the base station. The subscriber unit quickly increases transmission power while repeatedly transmitting the short code until the signal is detected by the base station. Once the base station detects the short code, it sends an indication to the subscriber unit to cease increasing transmission power. The use of short codes limits power overshoot and interference to other subscriber stations and permits the base station to quickly synchronize to the spreading code used by the subscriber unit.

摘要： A method for reducing distortion of an information symbol in an information symbol sequence. The information symbol sequence is transformed to a channel symbol sequence for modulating a carrier signal. The channel symbol sequence employs an M-ary signalling scheme. A received signal, which includes a channel symbol, a distortion value and a noise value, is demodulated as a received sample. An index value is determined from a previous information symbol interval. Using the index value the method selects an inverse distortion function for processing the received sample. A corrected sample is calculated using the inverse distortion function. The method determines a value of an information symbol, and a respective index, from the corrected sample. The method includes an adaption phase. The adaption phase adapts the nonlinear equalizer using a linear distortion function. The information symbol sequence is transformed to a channel symbol sequence of an M-ary signalling scheme with index value, for modulating a carrier signal. For each index value, the method includes the step of demodulating a training symbol sequence having pure symbol values as an observed sample sequence. A mean squared value and a mean value is calculated of the observed sample sequence. A mean squared value is calculated of the training symbol sequence. A cross correlation value is calculated. At least two simultaneous equations are solved for coefficients.

摘要： An apparatus for controlling hand-off in a spread-spectrum-CDMA-communications system, for radio devices moving from one cell to another, with each cell having a base station transmitting spread spectrum signals with generic-chip-code signals. A radio device includes a cellular antenna, matched filters, and detectors for detecting generic-chip-code signals embedded in spread-spectrum-communications signals. A comparator generates a comparison signal by comparing the relative time of arrival of a second detected signal with a first detected signal. A receiver-message-chip-code generator generates a replica of the message-chip-code signal, and a message mixer despreads the spread-spectrum-communications signal. A synchronization circuit synchronizes the receiver-message-chip-code generator to the first generic-chip-code signal for receiving the first spread-spectrum-communications signal or to the second generic-chip-code signal for receiving the second spread-spectrum communications signal, depending on a threshold. A control unit switches transmitting the message data, embedded in the first spread-spectrum-communications signal from the first base station, to the second spread-spectrum-communications signal transmitted from the second base station. Hand-off from an analog base station to a second base station utilizing spread spectrum is also possible.

摘要： A receiver receives signals and noise over a frequency spectrum of a desired received signal. The desired received signal is spread using code division multiple access. The received signals and noise are demodulated to produce a demodulated signal. The demodulated signal is despread using a code uncorrelated with a code associated with the desired received signal. A power level of the despread demodulated signal is measured as an estimate of the noise level of the frequency spectrum.
