摘要：
We proposes an integrated voice and data service for a multiple input multiple output (MIMO) system that assigns one subchannel for voice transmission and the remaining subchannels for data transmission. Two approaches are considered. In the first approach, voice is allocated on the subchannel associated with the largest singular value, while data is allocated on the remaining subchannels. In the second approach, voice and data are allocated on any of the unordered singular value channels. Based on the eigenvalue distribution of random Wishart matrices, closed form expressions for rate and power control are obtained to investigate the performance of the proposed schemes. The system performance is analyzed based on appropriate quality of service (QoS) indicators for voice and data services. Finally the analytical expressions are verified using Monte-Carlo experimental results.
