The error correcting and decoding, interleave and and DMT modulation and demodulation are analyzed in detail.
分析了信道编译码方法、 交织与解交织及DMT调制与解调等关键技术。
2
The algorithm is verified by experiments and the modulator can produce digital modulation signals with good EVM(Error Vector Magnitude) and spectrum mask.
通过验证，所产生的调制信号具有良好的误差向量幅度（EVM）和频谱特征。
3
After the unequal error protection of multilevel coded modulation is discussed in detail, a non-uniform signal constellation applied to 8ask modulation is designed.
