This paper introduces a principal concept of MIMO bit division and presents its performance with corresponding simulation results. When multiple antenna technique is applied to enhance the spectral efficiency, the original data stream should be divided in a proper way. We found that the way of dividing original data stream, if it is not cooperating well with the originally structured system, may lead to performance degradation. The key idea is dividing the original data bit stream without causing an undesired change of bit order at the output of bit-to-cell demux. | International Conference on Systems and Electronic Engineering ICSEE 2012 December 18-19 2012 Phuket Thailand Performance of MIMO Bit Division with Polarized MIMO DVB-T2 In-Woong Kang Ki-Hwan Suh Heung Mook Kim Jae Hyun Suh Youngmin Kim Suk Chan Kim and Hyoung-Nam Kim Abstract This paper introduces a principal concept of MIMO bit division and presents its performance with corresponding simulation results.

Introduction UHD Ultra High Definite tv standard supports 16 times bigger pixels per frame and about 4 times greater audio channels compared to HD High Definite TV standard. In addition higher frame rate greater number of bits per pixel and advanced color sampling result in an increase of amount of video and audio content. Even with an assistance of important progress in data compressing techniques the required transmission data rate is still big thus leading to the strong requirement of developing digital data transmission system. 256 4096 QAM modulation Turbo codes or LDPC codes and multiple antenna techniques are taken into account as some of key parts of such a development . DVB-T2 known as one of the most advanced digital terrestrial transmission DTT system offering higher spectral efficiency robustness and flexibility developed upon the DVB-T system 2 4 . Even though this digital broadcasting system can provide transmission rate enough for SD TV and HD TV contents still the transmission data rate is not sufficient for UHDTV service. Due to the lack of transmission data rate .
