| 摘 要： | 针对国内外少有关于在OFDM基带硬件实现自适应调制与编码的相关文献问题,采用改进的简单分组比特算法,提出了一种基于OFDM基带的自适应调制与编码硬件实现方案。设计的自适应调制与编码系统在20MHz下通过SMIC的CMOS 0.18μm工艺综合,仿真结果表明该自适应调制与编码方案具有面积小、功耗低等特点,特别适合在OFDM基带中使用。

| Abstract: | At present,there are few literatures about the hardware implementation of adaptive modulation and coding based on OFDM baseband both at home and abroad.With the improved simple block loading algorithm（SBLA）,a hardware implementation scheme of adaptive modulation and coding based on OFDM baseband was presented.The system was synthesized at 20MHz operating frequency in SMIC 0.18μm technology.Simulation results show that the scheme of adaptive modulation and coding has characteristics of small area and low power consumption,specifically suitable for OFDM baseband. |
