摘要： A method and serial detector for demodulating a phase-modulated signal are presented. In particular, a carrier phase estimator applies a phase estimate to an output of a matched serial filter. The filter output is matched to the first Laurent pulse of the received signal, and the phase estimate corrects for a phase bias introduced by using the first Laurent pulse. The method and detector are particularly valuable in Gaussian Minimum Shift Keying (GMSK) modulated systems and where then product of the bandwidth B and the bit rate Tb is less than about 0.3, and where a training sequence in a header of a burst system has a length L0 less than about 5000. Three estimates of phase offset are given, each taking the inner product of x and the conjugate transpose of either a or p; wherein x is a vector of data samples, a is a vector of pseudo symbols, and p is a vector of the data and ISI portions of the samples.

摘要： A method for timing a full duplex pulsed wireless communication system between first and second transceivers is disclosed. At least one of the transceivers is mobile. A propagation time between the first and second transceivers is calculated. A pulse period of the first transceiver is set to be twice the propagation time divided by an integer. The second transceiver's pulse period is set to be equal to the pulse period of the first transceiver to enable the first and second transceivers to transmit and receive pulses with a substantially reduced risk of a collision between pulses transmitted from the first and second transceivers.

摘要： Adaptive filtering is used to substantially cancel distortion in radio frequency (RF) signals. Such adaptive filtering can be used in an RF transmitting device to pre-compensate an RF signal with compensation (inverse) distortion to cancel inherent transmission path distortion from the RF signal. Adaptive filtering can also be used in a multi-carrier RF receiving device to cancel from a given carrier signal distortion due to cross talk from adjacent carrier signals. Adaptive filtering in an RF transceiver can be used to cancel from a received RF signal distortion arising from leakage of a transmit signal into the receive path.

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.
