Transmitting and receiving spread spectrum signals using continuous waveforms |
摘要 |
Systems and methods are described for transmitting and receiving spread spectrum signals using continuous waveforms. A method of transmitting a spread spectrum signal includes: generating a plurality of substantially continuous waveforms; summing the plurality of substantially continuous waveforms; modulating the summed plurality of substantially continuous waveforms to generate the spread spectrum signal; and transmitting the spread spectrum signal. A method of receiving a spread spectrum signal includes: generating a plurality of substantially continuous waveforms; summing the plurality of substantially continuous waveforms; modulating the summed plurality of substantially continuous waveforms with a code; mixing the modulated summed plurality of substantially continuous waveforms with the spread spectrum signal to produce a baseband signal; integrating the baseband signal; and detecting data.
