The present invention discloses a wideband CDMA mobile equipment capable of transmitting real-time bi-directional multichannel sound, which can be used in mobile station, handset or vehicle station. It comprises sending unit, receiving unit, central processing unit (CPU) and duplexer both connecting with the said sending and receiving unit. In the sending unit the stereo source is encoded into data stream, emitted after modulated by broadband CDMA into the prescriptive radio communication frequency range. In the receiving unit the radio signal carrying stereo is received with wideband CDMA and restored into digital code stream, then decoded into high quality of stereo sound. In combination of image encoding, the mobile communication system can provide not only bi-directional voice service, but also the services of the high quality of music or multichannel sound and image.
