Selection of Channel Coding for Low-Power Wireless Systems
AbstmctThe wireless communications world is moving towards the so-called 4 6 picture, by integrating many different subsystems. Some of them have to provide short-range connectivity at very low power, in order to enable hatteryopdrated sensors or devices. This low-power requirement can be achieved by selecting channel codes of high coding gain, However, the power consumption of encoding and dec...
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...
Source–Channel Coding for Wireless Networks
The aim of source coding is to represent information as accurately as possible using as few bits as possible and in order to do so redundancy from the source needs to be removed. The aim of channel coding is in some sense the contrary, namely to introduce redundancy that can be exploited to protect the information when being transmitted over a nonideal channel. Combining these two techniques le...
متن کاملCoding For MIMO Wireless Systems
MIMO wireless systems have received a great deal of attention recently, in part due to the promise of increased throughput, extended range, and improved reliability. Achieving the gains of the MIMO channel requires coding that can take advantage of these channel resources. This work studies the performance of different concatenated space-time coding and outer channel coding and develops some pr...
متن کاملSynchronization and Coding in Wireless Communication Systems
In the information age, modern communication systems and network applications have been growing rapidly to provide us with more versatile and higher bit rate services such as multimedia on demand (MOD), wireless local area network (LAN), 3G networks, and high-speed internet. In order to maintain the qualities of services, how to design a robust transceiver is a crucial issue. Symbol timing offs...
