For example, an uplink cellular scenario with a BS and two users UE1 and UE2.
Let's say, two users transmit to the BS at the same time via orthogonal channels. Is it possible to decode signal of a user at BS without any interference from another user? Can anyone please provide an answer with appropriate references?
By definition, "two orthogonal channels" means no interference to each other. Each channel is operated independently to the other, via any means, e.g. code division, (sufficient) frequency separation, time separation. Usually only approximate or near orthogonal can be achieved. That is there is still a little bit or mutual interference exist.
Orthogonality in certain dimension means that there is no interference. Interference occurs in frequency reuse scenarios like device-to-device communication while reusing cellular users, or for Non-orthogonal multiple access (NOMA) scenarios
