Spread spectrum communication system |
| abstract |
A spread spectrum communication system wherein spreading codes for in-phase and quadrature components are composed by addition and subtraction and the received signal is multiplied by these composed codes for despreading. The communication system comprises a transmitter generating in-phase and quadrature components. The transmitter includes a spreading circuit for spreading the in-phase and quadrature components. The system further includes a receiver, a phase correction circuit for correcting the phase of despreaded components, a rake combiner for combining the components corrected by the phase correction circuit and a circuit for outputting a combined signal and a delay detection circuit for delaying detection of the combined signal. The receiver also comprises a provisional judgment portion for judging the phase of a pair of the in-phase and quadrature phase components. The phase correction circuit corrects the phase according to the phase judged by the provisional judgment portion. |
