The paper mainly discusses the interference between LTE system and Analog TV in the frequency band 700MHz, with the simulation of the interference probability caused by the LTE cell based on energy detection of cognitive radio. The formula of interference distribution is based on RSMN network model, and focuses on the interference probability changed with the distance between LTE cell and Analog TV as well as the radius of LTE cell. That is, we can minimize effect of the interference to a certain extent by adjusting the parameters above.

Interference Estimation of LTE System and Analog TV Based on Cognitive Radio

The amplitude response characteristics of body channel in wireless body area networks versus body channel length and signal frequencies are analyzed in this paper.Then the energy detection formula based on the above body channel also are derived to formulate the energy detection algorithm in body area networks.In the end,this paper comes to the following conclusion: the detection possibility based on the derived energy detection algorithm versus channel length and signal frequencies is given in the condition of long enough detection time while signal energy changes from-128dBm to-110dBm.
