| Abstract: | This paper introduces the theory bases of direct sequence spread spectrum communication technology, and then a kind of DS communication system frame is given. The m-sequence is used as spread spectrum code sequence and the QDPSK is applied as modulation mode, then the signal of system transmitting module is emulated with the VHDL language in the MAX ＋ plus H software desk. The wave of emulation reaches the anticipation. |
