Outline of Final Research Achievements

In massive MIMO transmission, the transmitter and receiver have 100 or more antenna elements. To further increase the degree of integration of the antenna, reduction of overhead is considered to be essential. In this research, I researched a few overhead reduction methods. Moreover, I studied modulation and error control technique to reduce the effect of interference and error occurred by overhead reduction. In this research, basic studies have been performed widely, have revealed the numerical data useful for the future works. In addition, I also examined the error correction techniques, such as modulation and coding methods which are resistant to error and interference caused by reducing the overhead. Then, this study revealed a coded modulation scheme that can be efficiently transmitted at high-interference environments and error-correcting codes that are suitable for iterative interference canceller.
