摘要： A circuit and method for correcting timing of a received phase modulated signal. The method uses k most recently received data bits as an address for a lookup table 60. The lookup table includes reconstructed waveforms from which a timing weighing factor is determined. The received PM from time t1 is delayed, phase adjusted, and multiplied by the timing weighing factor, the product of which is used by a timing adjust block 50 to adjust timing of the PM signal at a time after t1. The circuit inputs a PM signal to a timing adjust block 50. The output is split between a matched filter 54 and a loop phase shifter 78. The matched filter feeds alternating I and Q bits into a register 58 that holds k data bits, which are used as an address for a lookup table 60. The output of the lookup table 60 becomes a timing weighing figure, which is multiplied 74 with an output of the loop phase shifter 78 and then input into the timing adjust block 50 for adjusting timing of a PM signal. Phase error may be corrected with minor additional components.

摘要： A circuit and method for correcting phase of a received phase modulated (PM) signal. The method uses k most recently received data bits, which alternate between in-phase I and quadrature Q bits, as an address for a lookup table 60. The lookup table outputs a phase figure 62 derived from a reconstructed waveform. When the most recent k bit is a Q bit, the complement 68 of the phase figure 62 is calculated to yield a phase correction. Otherwise, the phase figure is the phase correction, which is applied to adjust the phase of a delayed version of the received signal. The delayed, phase adjusted signal is then applied to correct the phase of a received signal. The circuit splits an input PM signal in parallel between a matched filter 54 and a delay block 76, 88. The matched filter output provides the input to a register 58 for storing the k data bits. The delay block holds the PM signal until it is input into a loop phase shifter 78 synchronously with the phase correction. The output of the loop phase filter is input, after filtering, to a primary phase shifter 52 that adjusts phase of a received PM signal.

摘要： A method for partitioning communication resource among multiple users partitions a portion of an available communication resource into a series of time-frequency slots, and allows multiple users to transmit in one of at least two available modes within a time-frequency slot. Preferably, one mode is time division of the time-frequency slot into time sub-slots, and another mode is code division of the time-frequency slot according to different spreading codes that spread an individual user's signal only within the subject time-frequency slot. Further details as to pilot signals, guard intervals, and payloads are described.

摘要： A multipoint-to-point CDMA communication system comprises a plurality of CDMA transmitting stations and a single CDMA receiving station, all of which are intercoupled to each other over one CDMA channel and one feedback channel. On the one CDMA channel, the plurality of CDMA transmitting stations simultaneously send respective CDMA signals to the receiving station. In the receiving station, respective time differences are measured between a reference clock signal and the spreading codes in the CDMA signals from each of the CDMA transmitting stations; and these time differences are indicated in respective error signals which the CDMA receiving station sends on the feedback channel to each of the CDMA transmitting stations. Each CDMA station responds to its error signals by time shifting its spreading code such that it arrives in the receiving station in synchronization with the reference clock signal. This synchronization enables interference between the spreading codes at the receiving station to be reduced by using codes which have minimal cross-correlation when their time difference is zero; and consequently, the maximum number of stations that can simultaneously transmit is increased.

摘要： A method of transmitting a spread spectrum signal in a single communication session between a transmitter and a receiver, stores a series of N unique waveform designs and a hopping sequence in a transmitter memory. A signal is transmitted to a receiver according to the hopping sequence using the plurality of N unique waveform designs. Preferably, each waveform design is characterized by a unique composite spreading code that is formed by at least some of a plurality of constituent code segments. Alternatively or additionally, the waveform designs may differ by any one or more of code length, symbol or chip timing or phase, frame or burst structure, chip offset, modulation, error control coding, encryption scheme, or scrambling code. A transmitter and receiver are also disclosed, as is the concept of appending chips between symbols to expand the universe of unique spreading codes without incurring an increase in processing gain.
