Provided is a receiving method for a terminal supporting at least two communication modes and at least one receiving algorithms. The receiving method includes the terminal recognizing at least one current communication mode and a channel status, selecting a receiving algorithm for each active communication mode according to the channel status by referring to a previously designed algorithm lookup table, and receiving a signal of each active communication mode using the selected receiving algorithm. In the receiving method, by activating a combination of optimal receiving algorithms with computational complexity allowed by a system according to at least one active communication mode of a terminal and a channel status, multiple services can be efficiently provided.
