    摘要: A method for multiple-input multiple-output (MIMO) collaborative communication in a wireless communication system includes at least one user equipment and M base stations performing collaborative communication with the user equipment. Here, M is an integer that is greater than or equal to 2. The method includes the following processes for each user equipment: a first level of MIMO pre-coding process is performed for each base station to acquire each first level of pre-coding matrix corresponding to each base station; a second level to the X-th level of MIMO pre-coding process is performed sequentially to acquire the second level to the X-th level of pre-coding matrices of the corresponding base stations. Here, X is an integer that is greater than or equal to 2. A pre-coding device, a user equipment and a wireless communication system related to the method are also provided.

    摘要: A method to establish a full-duplex audio connection over an asynchronous Bluetooth link between an audio terminal and a wireless audio device exchanges supported service classes and codecs between the audio terminal and the wireless audio device, negotiates a service class and a codec that are common to the audio terminal and the wireless audio device, and establishes an asynchronous audio connection between the audio terminal and the wireless audio device using the common service class and the codec. The audio connection established can depend on the software application desiring the audio connection plus the available service classes and codecs at the audio terminal and wireless audio device. For non-internet protocol (non-IP) audio applications, an ACL using AVDTP may be selected; for IP audio applications, an ACL using BNEP may be selected. Both AVDTP and BNEP can use codecs that support wide bandwidth audio.

    摘要: The ability to remove a watermark from an encoded image by reversible watermarking opens the possibility of various novel applications. Several such applications are detailed. One permits different classes of consumers to gain access to different versions of an image. A pristine image is intentionally degraded in some fashion, and distributed to consumers. By reference to one or more watermarks in the degraded image, some or all of the degradation can be removed, or transformed to a less-objectionable state. Through such arrangements, image consumers with different needs can gain access to versions of the image having differing qualities.
