The disclosure is directed to a method of multiuser superposition transmission (MUST) method and a transmitter using the same method. In one of the exemplary embodiments, the disclosure is directed to a method of multiuser superposition transmission (MUST) method used by a base station. The method would include not limited to: determining a first bit stream to be transmitted; encoding the first bit stream to generate an encoded first bit stream which has a plurality of binary levels per symbol; determining a first encoding rate for each of the binary levels of the encoded first bit stream, wherein at least two of the levels of the encoded first bit stream have a different code rate; and attaching a first plurality of redundancy bits based on the first encoding rate.c
