Abstract
本发明公开了一种通信方法,所述通信方法的步骤包括:生成发送数据;对发送数据进行扩频及上变频生成扩频数据;将扩频数据进行数模转换生成发送信号;发射发送信号;将所述发送信号模数转换为消除基准数据;接收外部信号;基于所述发送信号对所述外部信号进行射频干扰处理以重建转换为射频消除信号;将射频消除信号模数转换为待消数据;将所述待消数据与所述消除基准数据对消形成干扰消除数据;及对干扰消除数据进行解扩频。本发明还公开了一种通信系统,所述通信系采用带有正交性的扩频码进行扩频调制和解扩频能够使系统中的无用信号包括自干扰信号与接收到的外部信号的有用信号产生良好的隔离度,形成较好的接收效果。
Other Abstract
The invention discloses a communication method. The communication method comprises following steps: generating sending data; carrying out spread spectrum and up-conversion to the sending data so as to generate spread spectrum data; carrying out digital-to-analog conversion to the spread spectrum data so as to generate sending signals; sending the sending signals; carrying out analog-digital conversion to the sending signals so as to generate elimination reference data; receiving external signals; carrying out radio-frequency interference processing to the external signals basing on the sending signals so as to reconstruct and convert the external signals into radio-frequency eliminated signals; carrying out analog-digital conversion to the radio-frequency eliminated signals so as to generate data to be eliminated; carrying out cancellation to the data to be eliminated and the elimination reference data so as to generate interference eliminated data; and carrying out despread spectrum to the interference eliminated data. The invention also discloses a communication system. The communication system carries out spread spectrum modulation and despread spectrum by using spread spectrum codes with orthogonality; better isolation between the unusable signals in the system comprising self-interference signals and the usable signals of the received external signals is realized, and the relatively good receiving effect is realized.
