The Design and Implementation of the Wireless Data Modem Base on TTIB Technology
Jie Fu · 2001
Transparent tone in band(TTIB) and feedforward signal regeneration(FFSR) is a technology to combat the effects of multipath propagation delay and doppler effect in wireless channels. In this paper,the theory of TTIB and FFSR is described,and a design of the data modem is provided by using the digital signal processing technology to implement TTIB and FFSR.TTIB and FFSR can be used in data transmitting of HF single sideband transmitter receiver.
