中文摘要：
为改善V-BLAST/OFDM系统的性能,提出了子载波动态分配准则。该准则可以有效地利用多用户分集,明显提高V-BLAST/OFDM系统的整体性能。采用随机矩阵和排序统计的数学方法对取得的性能增益作了定量分析,仿真试验结果证明了分析的正确性。将取得的性能增益与空间分集系统中取得的多用户分集增益进行了比较,比较结果说明,将基于V-BLAST的多用户OFDM系统与子载波动态分配相结合,更能改善系统的整体性能。
英文摘要：
In order to improve the performance of V-BLAST/OFDM systems. This paper proposed the dynamic subcarrier allocation rules. The rules can effectively use multi-user diversity to improve V-BLAST/OFDM systems＇ performance greatly. The performance gain was analyzed quantitatively with order statistics and random matrix theories, and the analysis was validated by the simulation results. Moreover, compared with spatial diversity system, the dynamic subcarrier allocation combined with V-BLAST/OFDM system is showed to improve the system performance.
