<p>The invention discloses a wideband CDMA (WCDMA) mobile device being able to two-way transmit multi-channel sounds in real-time, for using in mobile stations, handsets and vehicle stations. It comprises a transmitting unit for multi-channel sounds, a receiving unit for multi-channel sounds, a central processing unit connecting with the transmitting unit and the receiving unit, and a duplexer. The transmitting unit encodes a stereo source into a data code stream, and modulates it in a WCDMA modulator onto a specified radio communication band in order to transmit. The receiving unit performs WCDMA reception on radio signals containing stereo sounds, recovers the digital code stream and decodes speech signals into high quality stereo sounds. By image encoding, mobile communication systems are made further to provide high quality music or multi-channel sound and image services while providing two-way speech services.</p> |
