9309008 McLaughlin The Principal Investigator is analyzing and designing quantizers for the compression and transmission of analog signals such as speech, images, video and music across noisy channels such as satellite links or telephone lines. The research considers joint source-channel codes, which are essentially source codes designed so that their outputs can be transmitted directly across a noisy channel without channel coding. The investigator is developing an asymptotic theory, giving insight and direction into the design of locally and possibly globally optimum noisy channel quantizers. Source-channel codes then will be designed to achieve or exceed the overall system performance of the traditional approach of tandem source and channel coding. The award provides support for three years.

9309008 McLaughlin首席研究员正在分析和设计量化器，用于压缩和传输模拟信号，如语音、图像、视频和音乐，跨越卫星链路或电话线等嘈杂通道。该研究考虑了联合源信道码，其本质上是设计的源代码，使其输出可以直接通过一个有噪声的信道传输，而无需信道编码。研究者正在发展一种渐近理论，为局部和可能的全局最优噪声信道量化器的设计提供见解和方向。然后，源信道编码将被设计为达到或超过传统的串联源信道编码方法的整体系统性能。该奖项提供为期三年的支持。
