simulating PAPR reduction with SLM method in STBC MIMO OFDM

为了提高MIMO-OFDM系统的数据传输率和频谱利用率,提出一种新的自适应算法。该算法在保证信道质量所需误码率和总发射功率的前提下,按照各个子载波衰落程度动态地分配比特和功率,使系统的总数据传输速率最大。理论分析得出,该算法降低了系统运算复杂度,能很大地改善系统的整体性能。(In order to improve data transmission rates and spectrum efficiency of MIMO-OFDM systems,this paper proposes a new adaptive algorithm. While the channel transmission quality to meet the requirements of a certain target BER(bit error rate) and total emissive power,according to each sub-carrier decline degree to adjust each sub-carrier modulation method freely,try to minimize the total data rate of system. Theory analysis shows the algorithm can reduce system complexity and improve overall performance of the ...)

全数字解调下16QAM信号的频偏估计的TD-GG算法实现。TD-GG算法是在TD和GG算法基础上提出来的，有较大的频偏估计范围和较好的估计精度，很好的解决了传统的非数据辅助频偏估计算法中估计范围和精度不能兼顾的问题，而且这种算法易于实现。(Digital demodulation under the 16QAM signal frequency estimation TD-GG algorithm. TD-GG algorithm is based on the TD and the GG algorithm is proposed, and have greater range and better frequency estimation of estimation accuracy, a good solution to the traditional non-data aided frequency offset estimation algorithm to estimate the range and accuracy not take into account the issue, and this algorithm is easy to achieve.)
