摘　　要：给TD-LTE系统中,资源映射是将经过信道编码,交织,调制之后的数据映射到OFDMA时频符号上的过程。资源映射不仅是基带信号产生流程的重要部分,而且是实现用户资源灵活分配优势的关键。此外,由于LTE系统的一个基本特征是支持更大的系统带宽,而吞吐量与系统带宽成正比,对资源映射的研究能很好地协调系统带宽和吞吐量之间的矛盾。所以资源映射对整个系统来说具有重要意义,保证其稳定性和高性能尤为关键。本文基于通用处理器实现了资源映射的功能。In TD-LTE system,Resource-Mapping is the process of mapping data after Channel coding,Interleaving and Modulation to the OFDMA symbol.The Resource-Mapping is not only a important part of the baseband signal generation process, but also a key point to achieve the flexibility of the resource allocation. In addition, since LTE intends to support large bandwidth, which is proportional to system throughput, research of Resource-Mapping can coordinate the contradictions between system bandwidth and throughput vcell. Therefore, Resource-Mapping is the one of the most important part in the whole system, it is critical to ensure its stability and high efficiency performance.
