N-body-extended Channel Estimation for Low-Noise Parameters
The notion of low-noise channels was recently proposed and analyzed in detail in order to describe noise-processes driven by environment [M. Hotta, T. Karasawa and M. Ozawa, Phys. Rev. A72, 052334 (2005) ]. An estimation theory of low-noise parameters of channels has also been developed. In this report, we address the low-noise parameter estimation problem for the N -body extension of low-noise...
متن کاملchannel estimation for mimo-ofdm systems
تخمین دقیق مشخصات کانال در سیستم های مخابراتی یک امر مهم محسوب می گردد. این امر به ویژه در کانال های بیسیم با خاصیت فرکانس گزینی و زمان گزینی شدید، چالش بزرگی است. مقالات متعدد پر از روش های مبتکرانه ای برای طراحی و آنالیز الگوریتم های تخمین کانال است که بیشتر آنها از روش های خاصی استفاده می کنند که یا دارای عملکرد خوب با پیچیدگی محاسباتی بالا هستند و یا با عملکرد نه چندان خوب پیچیدگی پایینی...
Channel Estimation Theory of Low-Noise Multiple Parameters: Attainablity Problem of the Cramér-Rao Bounds
For decoherence processes induced by weak interactions with the environment, a general quantum channel with one noise parameter has been formulated. This channel is called low-noise channel and very useful for investigating the parameter estimation in the leading order. In this paper, we formulate the low-noise channel with multiple unknown parameters in order to address the simultaneous achiev...
متن کاملNoise Reduction for Optical OFDM Channel Estimation
I N recent years, Orthogonal Frequency Division Multiplexing (OFDM) has been proposed for optical long-haul communications due to the ease of equalization of the dispersiongoverned fiber optical channel [1]. The approaches pursued can be distinguished into two groups: First, there are coherent optical systems which use quadrature modulation at the transmitter and zero-IF (Intermediate Frequency...
متن کاملChannel Noise Robustness for Low-bitrat
In remote (or distributed) speech recognition , the recognition features are quantized at the client, and transmitted to the server via wireless or packet-based communication for recognition. In this paper, we investigate the issue of robustness of remote speech recognition applications against channel noise. The techniques presented include: 1) optimal soft decision channel decoding allowing f...
