That is, we fixed the values of $\alpha_1$ and $\alpha_2$ irrespective of the channel conditions. The awgn function first measures the power (P) of x. Here are the assumptions we are going to make: A few pointers about these assumptions: (i) In real time systems, NOMA performs better when one of the users is closer to the BS (also called the near/strong user) and the other user is far away (far/weak user). Found insideThis book intends to provide highlights of the current research topics in the field of 5G and to offer a snapshot of the recent advances and major issues faced today by the researchers in the 5G physical layer perspective. h is called  impulse response of Rayleigh channel? propose a power allocation algorithm for NOMA system and measure the energy efficiency performance of the networks by using the unit of bits per Joule [30]. However, in this paper, we investigate energy . In our next post, we will see BER simulation of NOMA in a Rayleigh fading channel, where the users have different channels and are located at different distances from the BS, which is a more realistic case. 3226-3237, 2016. by simultaneously allowing multiple users at same frequency/time/code, it achieves the capacity of the Gaussian broadcast channels [4], [6]. Matlab code for SIC (successive Interference. Working towards final deployment, this book updates the research community on the current mmWave Massive MIMO roadmap, taking into account the future emerging technologies emanating from 3GPP/IEEE. 1.1 Motivation, Background, and Related Work In this post, we will see how SIC is carried out to decode the superposition coded signal at the receiver side. We will see that NOMA works even under this assumption. After BPSK modulation and choosing a 1 = 0.75 and a 2 = 0.25, we obtained the superposition coded signal x, as shown below: Before decoding, let us take a look at SIC al. For example, demonstrating NOMA power allocation policies, the use of successive interference cancellation in some users with For downlink NOMA, non-orthogonality is achieved by introducing the power domain, either in time/frequency/code domains, for user multiplexing. Practical implementation of NOMA in cellular networks requires high computational power to implement real-time power allocation and successive interference cancellation algorithms.
