-The number of mobile devices, IoT devices, and their applications is increasing day by day in recent years and further going to increase in coming years. These applications and devices demand large connectivity, high throughput, and low latency which can be possible only in the B5G or 6G. The effective utilization of the spectrum is done by multiple access techniques which facilitate the spectrum to accommodate a large number of users. The 5G has different new technologies to support the massive user demand and high-speed data rate. The non-orthogonal multiple access scheme (NOMA) is considered for the B5G or 6G. The NOMA offers a massive number of user connectivity in contrast to the OMA which is an orthogonal multiple access scheme. The performance evaluation of the SCMA is investigated and recent advancement in the field of NOMA is discussed in this paper. The BER performance of Capacity-based codebook design and codebook design based on lattice constellation is evaluated on the two different channels i.e AWGN and Rayleigh fading channel. The behavior of capacity-based codebook design is better than lattice-based codebook design. The performance of both codebook designs surpasses AWGN in contrast to the Rayleigh fading channel by the multipath available in the Rayleigh Fading channel.

“…In the literature [1,4,[10][11][12][13][14][15], NOMA techniques are categorized into two: power domain (PD) and code domain (CD). In CD-NOMA, the users occupy more than one orthogonal resources for communication and they are distinguished by different codewords.…”

This paper presents a sparse code multiple access (SCMA) system with massive antennas at the base station. This system is referred to as M-SCMA system. A spectrally-efficient and massive access next-generation wireless network is realized through massive antennas and non-orthogonal SCMA techniques. Two detection algorithms, namely, modified message passing algorithm (MMPA) and extended message passing algorithm (EMPA) are proposed to detect multiple users' symbols in M-SCMA. A deep learning (DL)-based detection scheme is also proposed for M-SCMA so as to avoid channel estimation and to lower the detection complexity. Numerical results show that the DL-based detection has similar performance as MMPA even when the channel information is not estimated explicitly. Furthermore, authors also establish the sum rate trade-off between SCMA and orthogonal multiple access in a massive antenna system. The impact of various M-SCMA parameters such as the number of antennas and the overloading factor, on the proposed DL, MMPA, and EMPA-based detection are also investigated.

“…The main goal of designing an online piano teaching system is to address the challenges that arise from traditional face-to-face teaching, such as issues related to time, physical location, cost, and transportation (Cui & Shuang, 2019). This platform aims to leverage the rapidly expanding network as a platform for effective piano learning, taking into consideration the specific requirements of piano education by synthesizing various societal resources to facilitate successful piano learning.…”

The application of computer technology has revolutionized and promoted the traditional mode of piano teaching. Nowadays, many companies and institutions have begun to apply computer technology to online piano teaching. This paper analyzes the difficulties faced by students in piano teaching and the development of piano assistant practice and summarizes the demands of parents, teachers, students, and principals for online piano teaching system. Based on this, this paper designs and implements an online piano teaching system without special hardware. This system improves the existing maximum logarithm MPa algorithm and improves the detection performance while keeping the complexity low. Combined with the special structure of parallel projection, a generalized automaton model of hybrid system is proposed, and five elements are used to describe the continuous and discrete behaviors in the hybrid subsystem. It not only keeps the advantage of low complexity of the original Max log MPa algorithm, but also obtains better detection performance.
