Experimental performance analysis of a new multicode radio transmission scheme under inter-vehicle mobile communication environments

摘要

In this paper, in order to verify the feasibility of an new orthogonal multicode transmission scheme based on cyclic extended and shifted M-sequence under inter-vehicle mobile communication environments, we utilized a prototype and carried out a field transmission experimentation by using our developed prototype. Especially, we brought our prototype to a highway course. At the highway course, we measured several transmission performances of our proposed prototype, i.e. received power, delay profile characteristic, and BER performances, under high mobility environment. For the transmission frequency, we utilized microwave bands which include 5 GHz band, which frequency are expected for the 4th generation mobile communication system. As a result, we can realize 4.608 Mbps error -free data transmission under inter -vehicle mobile communication environment when we use 20 dBm as a transmission power. We show some experimental concrete results and discuss our proposed multicode transmission scheme.
