Field experiments of mobile reception with a space division multiplexing MIMO transmission system — Comparison with mobile reception performance of ISDB-T

摘要

We are developing a next generation terrestrial broadcasting transmission system for handheld and mobile reception on a space division multiplexing MIMO (SDM-MIMO) OFDM transmission system which uses two transmission antennas and two reception antennas. This paper describes field experiments on mobile reception comparing ISDB-T and SDM-MIMO reception areas in Kumamoto Prefecture. As a result, the transmission parameters of SDM-MIMO to be the same as those for ISDB-T with 4-branch space diversity was found to be a 16QAM and coding rate of 1/2.
