| 摘 要： | 针对一般无线通信系统抗干扰、抗噪声以及抗多径性能力差的缺点,提出了一种基于FPGA的直接序列扩频系统设计。该设计采用63位的pn码作为扩频调制的码序列,在发送端,对信息码进行扩频调制;在接收端,对收到的扩频调制信号进行解扩,增强了系统的抗干扰性和可靠性。同时在Altera公司的Quartus II软件中,使用硬件描述语...

| Abstract: | General wireless communication system has many has many shortcomings,for example the poor ability of anti-interference,anti-jamming and anti-multipath performance.This paper proposes a direct sequence spread spectrum system based on FPGA.This design uses 63 bits of code series as spread spectrum modulation code sequences.When sending information code,the information code is modulated by PN code;in the receiver,the information is demodulated.this process improve the system's performance.Both VHDL and princip... |
