MIMO-OFDM通信系统中的信道容量研究

Since the available frequency spectrum is becoming scarce, high spectrum efficiency is required for future communication systems. OFDM and MIMO combined communication system can achieve a higher spectrum efficiency than traditional cases, which makes it an attractive candidate for high datarate wireless communication applications. MIMO-OFDM communication theories are investigated in this thesis. The relationship between capacity and SNR is simulated with MATLAB simulation software under self-adapted power allocation. Based on the power allocation by using Singular Value Decomposition (SVD), Water-Filling algorithm is studied to obtain the optimal system capacity.
