摘要:

NOMA)技术的代数设计的基础上进行了研究。提出了一种改进的基于射影几何的低密度扩频序列设计方法。在其比特出错率(BER)性能方面,我们提出的改进的LDS码集优于现有的LDS设计在频率非选择性瑞利衰落和加性高斯白噪声(AWGN)信道。我们证明了实现最佳BER取决于最小距离。

英文摘要:

NOMA) technique based on an algebraic design is studied. We propose an improved low-density spreading (LDS) sequence design based on projective geometry. In terms of its bit error rate (BER) performance, our proposed improved LDS code set outperforms the existing LDS designs over the frequency nonselective Rayleigh fading and additive white Gaussian noise (AWGN) channels. We demonstrated that achieving the best BER depends on the minimum distance.
