This paper studies the characters of wireless fading channel based on TD-LTE, and it is critical of multipath effect and Doppler effect. So there design a math channel model combining these factors. And then set up link in Matlab to analyse the model. Through simulating we can optimize the model. After that it is implemented by FPGA of final determined math channel model. Using TD-LTE baseband signal as driven signal, this model is simulated and implemented in ModelSim platform. Through comparison and analysis the error between the channel impulse of the model and the result of Matlab link, we can obtain that the relative error is very little. So it can confirm reliability of this channel simulator.

Fading channel modeling is generally defined as the variation of the attenuation of a signal with various variables. Time, geographical position, and radio frequency which is included. Fading is often modeled as a random process. Thus, a fading channel is a communication channel that experiences fading. In this paper, the proposed system presents a new design and simulate a wireless channel using Rayleigh channels. Rayleigh channels using two approaches (flat and frequency-selective fading channels) in order to calculate some path space loss efforts and analysis the performance of different wireless fading channel modeling. The results show that the bite error rate (BER) performance is dramatically improved in the value of signal to noise ratio (SNR) is equal to 45dB. Finally, the experimental results show that the proposed method enhances the performance of fading channel modeling by reducing the error of BER when the SNR is reduced also. Moreover, the more accurate model is Rayleigh model which can be considered for developing fading channel model.

Two pulse waveforms are designed and analyzed for 60GHz pulse modulation systems. An indoor frequency selective fading channel model is introduced for single user 60GHz TH-PPM systems. The capacity with this channel model of a 60GHz TH-PPM system based on the designed pulses is derived. Performance results are presented to illustrate the effects of the pulse waveforms and channel properties on the channel capacity.
