Techniques of defining a transmission scheme for NB-IoT data include determining the TBS based on 16-quadrature amplitude modulation (QAM) analysis but use quadrature phase-shift keying (QPSK) for modulation. For example, a base station (eNB) may determine that a UE is configured to receive or...
16-QAM(16 Quadrature Amplitude Modulation)是一种调制技术,通过将信息分配到四个象限的相位和幅度组合中,来实现数据传输的高效性。在此基础上,16-QAM能在同样的带宽中传输更多的数据,因此成为5G以及未来通信系统的重要组成部分。简单来说,16-QAM能够让我们在更短的时间内获取更多的信息,这对于我们日常生活的各个方...
Tabular difference between 16-QAM, 64-QAM and 256-QAM Following table mentions difference between 16-QAM, 64-QAM and 256-QAM modulation techniques. The purpose of KMOD here is to achieve the same average power for all the mapped symbols (i.e. average power of 1). ...

分层调制(Hierarchical Modulation, HM)是一种用于提高数字通信系统灵活性和效率的技术。它通过将数据分成不同优先级的多层,并针对不同层使用不同的调制和编码方案,从而在确保高优先级数据可靠传输的同时,尽可能提高低优先级数据的吞吐量。本研究将重点探讨HM 4/16 QAM(Quadrature Amplitude Modulation,正交幅度调制)的...

16-qam modulation I have a problem with 16qam modulation. I want to modulate with 16qam a binary signal and as I know 16-qam supposed to separate the signal into groups of 4 bits and maps them each one to a complex number. The problem is that I try to do this with 16 bits but I...
