Abstract

Orthogonal Frequency Division Multiplexing (OFDM) is one of the latest wireless communication technologies, which aids transmission with the high data rate, reliability, and spectral efficiency. Our study involved simulation of an OFDM system using 32-QAM symbol mapping, over a Rician channel model. A comparative analysis involving three different detection techniques: maximum likelihood, minimum mean square error, and zero-forcing in terms of MSE and BER are carried out. The analysis shows that amongst the detection techniques, Minimum Mean Square Error yields the lowest values of MSE and BER, for SNR ranging from 0 to 30 dB.
正交频分复用信道的MSE和BER分析
正交频分复用技术(OFDM)是一种最新的无线通信技术,具有数据传输速率高、可靠性好、频谱效率高等优点。我们的研究涉及使用32-QAM符号映射的OFDM系统仿真,在一个典型的信道模型上。比较分析涉及三种不同的检测技术:最大似然、最小均方误差和零强迫在MSE和BER方面进行。分析表明,在检测技术中,最小均方误差产生的MSE和BER值最低,信噪比范围为0到30 dB。
