Joint Source and Channel Coding for MIMO Systems∗
A significant amount of recent research has focused on characterizing the diversitymultiplexing tradeoff region in multiple antenna wireless systems. In this paper we focus on finding the point on this diversity-multiplexing region that minimizes endto-end distortion. Our goal is to find the optimal balance between the increased data rate provided by multiplexing versus the error protection pro...
متن کاملAnalog Joint Source-Channel Coding for MIMO-OFDM Systems
Analog Joint Source-Channel Coding (JSCC) has been shown to approach the optimal distortion-cost tradeoff when transmitting over AWGN channels. In this work we consider analog JSCC over frequency-selective channels using Orthogonal Frequency Division Multiplexing (OFDM) modulation and multiple antennas at transmission and/or reception, i.e. using a MIMO-OFDM system. Due to its high complexity, ...
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...
Analog joint source-channel coding over MIMO channels
Analog joint source-channel coding (JSCC) is a communication strategy that does not follow the separation principle of conventional digital systems but has been shown to approach the optimal distortion-cost tradeoff over additive white Gaussian noise channels. In this work, we investigate the feasibility of analog JSCC over multiple-input multiple-output (MIMO) fading channels. Since, due to co...
متن کاملJoint Source, Channel and Space-time Coding of Progressive Sources in MIMO Systems
The optimization of joint source and channel coding for a sequence of numerous progressive packets is a challenging problem. Further, the problem becomes more complicated if the space-time coding is also involved with the optimization in a multiple-input multiple-output (MIMO) system. This is because the number of ways of jointly assigning channels codes and space-time codes to progressive pack...
