The Lte Uplink Channel Interference Suppression Merging Technology Algorithm And Implementation

As the last mobile communication technology, LTE(Long Term Evolution) is becoming the master role for the4G standard by its so many technology advantages such as high throughput, high frequency using ratio, low time delay, back-forwards compatibility and so on. OFDM can get high frequency using ratio, but at the same time, it makes the colored interference unavoidable. To deal with the same frequency interference issue, the interference rejection technologies are coming out. By the research of Interference Rejection Combining arithmetic based on Minimum Mean Square error Estimation, this paper completed the following task:[1]. Deduced Max Ratio Combining (MRC) and Interference Rejection Combining equilibrium formula and compared the performances between MRC and IRC arithmetic for8antennas by simulations;[2]. Compared the performances among MRC and IRC arithmetic for2antennas and IRC arithmetic for8antennas; Made an equivalent transform for IRC arithmetic by Cholesky decomposition to reduce the actual computational complexity;[3]. Tested and verified the performances of IRC equilibrium technology on Alcatel-Lucent TD-LTE eNode B platform.
