A Quantum Broadcasting Problem in Classical Low Power Signal Processing
We pose a problem called “broadcasting Holevo-information”: given an unknown state taken from an ensemble, the task is to generate a bipartite state transfering as much Holevo-information to each copy as possible. We argue that upper bounds on the average information over both copies imply lower bounds on the quantum capacity required to send the ensemble without information loss. This is becau...

برای پردازش سیگنال آنالوگ در شبکه های عصبی ، معمولا نیاز به یک واحد حافظه آنالوگ احساس میشود که بدون احتیاج به a/d وd/a بتواند بطور قابل انعطاف و مطمئن اطلاعات آنالوگ را در خود ذخیره کند. این واحد حافظه باید دارای دقت کافی ، سرعت بالا ، توان تلفاتی کم و سایز کوچک باشد و همچنین اطلاعات را برای زمان کافی در خود نگهدارد. برای پیاده سازی سیستمی که همه این قابلیتها را در خود داشته باشد، کوشش...

In this paper, we present a new adaptive error-cancellation (AEC) technique, denoted as multi-input–multi-output (MIMO)-AEC, for the design of low-power MIMO signal processing systems. The MIMO-AEC technique builds on the previously proposed AEC technique by employing an algorithm transformation denoted as MIMO decorrelating (MIMO-DECOR) transform. MIMO-DECOR reduces complexity by exploiting co...
متن کاملLow power digital signal processing
This thesis introduces a novel approach to programmable and low power platform design for audio signal processing, in particular hearing aids. The proposed programmable platform is a heterogeneous multi-processor architecture consisting of small and simple instruction set processors called mini-cores as well as standard DSP/CPU-cores that communicate using message passing. The work has been bas...
متن کاملUltra low power digital signal processing
he wide-spread and growing use of portable, battery-powered devices like cellular telephones, audio-capable personal digital assistants (PDAs), MP3 players and similar applications has resulted in an increasing demand for miniature, ultra low-power digital signal processing (DSP) technology. Many of these devices make heavy use of digital signal processing techniques like modulation, demodulati...
