In Non Orthogonal Multiple Access NOMA, Why do we use SIC which is complex method for demodulation rather than using joint demodulation ?

in NOMA to detect the composed signal, low power user need to detect all higher power users and cancel them before detecting its own. Why this low user does not detect its message by cancelling...

IN (NOMA) we us SIC at receiver to detect and cancel the signals sequentially, why we don`t cancel undesired signals together to speed up process?

In Non Orthogonal Multiple Access we user Successive Interference Cancellation at receiver side to detect the more power full signal and cancel it until reaching the desired signal based on...
