TTIB是一种可抵抗无线信道中多径时延及多谱勒频移而引起信号衰落的一种高效的频谱技术。在文献[1]原有的两位数字信号的基础上,使用VHDL硬件编程语言建模、仿真,并基于FPGA硬件平台实现了一个八位数字信号的TTIB处理系统。结果表明,有效的实现了TTIB处理。
TTIB is an efficient spectrum technique that can resist the signal fading caused by multipath delay and Doppler shift in wireless channel. Based on the original two digital signals in literature [1], a VHDL hardware programming language is used to model and simulate. Based on the FPGA hardware platform, an eight-bit TTIB processing system is realized. The results show that the TTIB processing is effectively implemented.
