How does successive interference cancellation work?
Successive Interference Cancellation (SIC) is a technique used by a receiver in a wireless data transmission that allows decoding of two or more packets that arrived simultaneously (in a regular system, more packets arriving at the same time cause a collision).
What is sic in noma?
NOMA adopts the principle of successive interference cancellation (SIC) algorithm at the receiver's side to segregate user's information. However, during SIC process, information of the user(s) with weaker channel gain is extracted by user(s) with stronger channel gain.
Why Noma is not used in 5G?
The primary reason for adopting NOMA in 5G owes to its ability of serving multiple users using the same time and frequency resources. There exist two main NOMA techniques: power-domain and code-domain. Power-domain NOMA attains multiplexing in power domain, whereas code-domain NOMA achieves multiplexing in code domain.
How does Noma work in 5G?
NOMA uses superposition coding at the transmitter such that the successive interference cancellation (SIC) receiver can separate the users both in the uplink and in the downlink channels. NOMA was proposed as a candidate radio access technology for 5G cellular systems [2, 3].
