Transmission and the method and apparatus for receiving data, by the offer for executing iterative MUD. The device includes: a kind of reception transmission signal, and generates reception signal, and the single-carrier signal that transmitting signal modulation generates is via modulated process, each dedicated user is in wireless communication system; A kind of interference canceled signal generator generates an interference canceled signal by eliminating signal interference using the signal of bolt wave relative to signal is received, and signal is by other users; With the signal generator of demodulation, for generate this bolt wave signal to receive signal demodulate, demodulation process is by using the interference canceled signal, demodulation process is exclusively for each user, the wherein signal of the bolt wave generates the signal of interference canceled signal and above-mentioned generation bolt wave and is adopted the signal as final demodulation at least once by executing.
