| 摘要 |
<p>The invention relates to a code division multiple access transmitter, in which the data to be transmitted drive a frequency synthesizer which in turn generates the clock of a pseudo-noise code generator with a slight frequency offset. In the corresponding receiver, said frequency offset observed at the transmitting side affects proportionally a correlation magnitude. At the end of each correlation period, the correlation results are then compared to thresholds and the demodulated data are finally extracted. Application: mobile communications.</p> |
