we present a practical link adaptation algorithm for MIMO-OFDM systems. The proposed solution is based on sounding the channel periodically and choosing the optimal mode that will maximize the throughput or energy efficiency (EE) while satisfying the application’s quality of service (QoS) requirements. In addition, we address practical problems such as the computational complexity of the algorithm and determination of sounding period by novel closed form solutions and iterative algorithms. Realistic link level simulations confirm that the proposed solution achieves significant improvement over existing link adaptation algorithms when the aim is to maximize the throughput, and provides orders of magnitude gain in energy efficiency compared to poorly chosen fixed modes when used for energy efficiency maximization purposes. The resulting algorithms are implemented on a real time MIMOOFDM testbed, and we report on the experimental results.

说明：  像素聚类区域成长法－－ 顾名思义，此方法从一个种子像素开始，通过如平均灰度，组织纹理及色彩等性质的判断，将具有类似性质的像素逐一纳入所考虑的区域中，使此区域由种子逐渐成长成一个性质相似的图像区块。(pixel clustering method regional growth-- the name implies, this method from a seed pixels, through such as average gray, the color and texture organizations such as the nature of judgment, with similar to the nature of each pixel into consideration the region, so this area has gradually grown from seed into a nature similar to the image block.)
