5G NOMA Training
Non-Orthogonal Multiple Access (NOMA) Training
There are nearly 7 billion mobile phone users on the planet – with more usage on the way as 5G rolls out across the U.S. and other countries. This is why telecom companies are excited about NOMA (non-orthogonal multiple access).
Today’s wireless networks allocate radio resources to users based on the orthogonal multiple access (OMA) principle. However, as the number of users increases, OMA based approaches may not meet the stringent emerging requirements including very high spectral efficiency, very low latency, and massive device connectivity.
Non-orthogonal multiple access (NOMA) principle emerges as a solution to improve the spectral efficiency while allowing some degree of multiple access interference at receivers.
The NOMA basic concept goes something like this:
In downlink NOMA, the transmit signal from the BS and the received signal at both UE receivers is composed of a superposition of the transmit signals of both UEs.
Thus multi-user signal separation needs to be implemented at the UE side so that each UE can retrieve its signal and decode its own data. This can be achieved by non-linear receivers such as maximum likelihood detection or SIC (Successive Interference Cancellation)
For the case of SIC, the optimal order for decoding is in the order of the decreasing channel gain normalized by noise and ICI power. Based on this order, we can actually assume that any user can correctly decode the signals of other users whose decoding order comes before the corresponding user.
In a two-UE case (assuming that UE-2 does not perform interference cancellation since it comes first in the decoding order) UE-1 first decodes UE-2 signal, and subtracts its component from total received signal, and thus it gets its own signal component and decodes it, without interference from UE-2 signal.
NOMA uses the power domain to separate signals from each other. In this way, NOMA gives a new dimension in which signals can be separated and given access to a base station. This technique that has not been used within 2G, 3G or 4G before.
Key features of NOMA include:
- Improved SE (spectrum efficiency): NOMA exhibits a high SE, which is attributed to the fact that it allows each resource block to be exploited by multiple users.
- Relaxed channel feedback: In NOMA, perfect uplink CSI is not required at the base station (BS). Instead, only the received signal strength needs to be included in the channel feedback.
- Low transmission latency: In the uplink of NOMA, there is no need to schedule requests from users to the BS, which is normally required in OMA schemes. As a result, a grant-free uplink transmission can be established in NOMA, which reduces the transmission latency drastically.
- Ultra-high connectivity: With the capability to support multiple users within one resource block, NOMA can potentially support massive connectivity for billions of smart devices. This feature is quite essential for IoT scenarios with users that only require very low data rates but with massive number of users.
Non-Orthogonal Multiple Access (NOMA) Training Course by Tonex
Non-Orthogonal Multiple Access (NOMA) Training is a future 5G Technology (5th generation wireless systems or mobile networks using non-orthogonal multiple access) that covers the next major phase of wireless and mobile telecommunications standards beyond the current 4G/IMT-Advanced standards with a focus on novel NOMA modulation and coding scheme for the air interface.
Further, 5G Technologies Using NOMA Training will review major aspects of 5G technologies and will introduce most dominant technologies and architectures in the near future which make 5G technology. 5G networks are rolling out now. Compared with 4G/LTE cellular systems, 5G wireless communication systems (5G) are expected to provide higher spectral and energy efficiency and throughput growth. Key to this additional spectral and energy efficiency promise includes novel air interface techniques such as NOMA.
In contrast to orthogonal multiple access (NOMA) techniques such as orthogonal frequency-division multiple access (OFDM) and orthogonal frequency-division multiple access (OFDM), NOMA makes use of the power domain to modulate signals over a larger bandwidth. Accordingly, devices can communicate over the same total bandwidth, but at different power levels.
Using NOMA Training, attendees will learn the key 5G wireless communication networks cellular architecture and key technologies for 5G communication networks, with an emphasis on NOMA.
5G Wireless using NOMA training covers the fundamental 5G wireless communications including, channels, antennas, propagation, 3GPP New Radio (NR), Next Generation (NexGen), issues surrounding emerging 5G wireless LAN and cellular/backhaul applications. Learn how 5G networks could provide more data bandwidth and less latency using built-in computing intelligence to handle more data more efficiently than today’s 4G networks. 5G networks will leverage more benefits of Moore’s Law due to the convergence of communications and computing technologies and platforms.
5G Technologies Using NOMA Training covers concepts, services, technologies and network components behind 5G wireless. Find out how 5G wireless networks will be much smarter and faster than 4G. New trends such as machine-to-machine communication, self-driving cars, smart cities, connected society, Internet of Things (IoT), broadcast-like services, lifeline communications in times of natural disaster will be part of the new 5G wireless services.
