1. A transmitter device i for a secure channel training method applied to a power domain non-orthogonal multiple access system comprising:
a plurality of transmitters and receivers, wherein the transmitter device i is configured to:
estimate a channel between receiver device j and transmitter device i;
estimate a channel between receiver device j+1 and transmitter device i;
apply a channel processing block to encode the estimated channels between transmitter device i and receiver devices j and j+1; and
transmit a signal of said encoded channels to receiver device j+1 containing information regarding the estimated channels between transmitter device i and receiver's devices j and j+1.
