|We will conduct field tests to verify the system’s effectiveness in the 1.2-GHz and 2.3G-Hz bands and investigate
the technical requirements related to a switch-over of FPU frequencies.
| * 1 FPU (Field Pick-up Unit) : Wireless system for transmitting video material
* 2 Space-time trellis coded MIMO(STTC-MIMO) transmission : A MIMO method in which two transmitting branches perform convolutional coding with distant mapping points for different data and two receiving branches are used in Viterbi decoding to reconstruct the transmitted data.
* 3 Macro-diversity : A method that gathers, selects, and combines the signals received by multiple distant base stations. It greatly improves the diversity effect in comparison with the previous method of selection after demodulation for each base station.
