OFDM is increasingly utilized in the field of mobile radio because it is robust over phasing or multipath. However, the symbol period should be short in order to lower the normalized fdTs in the usage for high speed mobile. It is difficult to secure high bit rate in the narrow occupied bandwidth. In this report, we evaluated our picture receiving system, where receivers were decentralized around the necessary receiving area and connected by optical fibers for diversity composition, and fdTs was set as relatively high by plotting the frequency central value from the guard correlation to Doppler effect. Also, we revised the equivalent processing method at the frequency band edge. The results show the system enables a narrow band real-time wireless picture transfer with better frequency usage efficiency from high speed mobile. |
