Precise BER Analysis of 1⁄2 and 2⁄3 rated RS-CC Concatenated Coded for Digital Image Transmission in OFDM System
We introduce an analytical approach to evaluate bit error rate (BER) expression is derived for an OFDM system with PSK and QAM encoded image signal are transmitted over AWGN and fading channel models. Different system configurations including time-domain differential modulation, frequency domain differential modulations, delay spread of channels are considered in the exact BER analysis. Both an...
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...
Performance Analysis of Concatenated RS-CC Codes for WiMax System using QPSK
In this paper we present a practical RS-CC concatenated coding scheme in the WiMAX system. In our proposed scheme, the information is first coded at the transmitter using RS-CC coder and then decoded at the receiver using RS-CC decoder for different channel models. This paper presents Bit Error Rate for Reed-Solomon Convolutional Coding (RS-CC) based WiMax system with QPSK modulation scheme und...
متن کاملEfficient Convolutional Code Algorithm for Concatenated RS- CC Codes in Multipath Environment
In the wireless communication, the error detection and correction techniques are widely used to achieve higher transmission efficiency. While transmitting the data, some coding techniques are deployed that provides the coding gain depending on its error correcting capability. Coding gain allows the wireless communication at lower transmit power level while maintaining low BER. Reed Solomon – Co...
متن کاملImproved Channel Estimation for DVB-T2 Systems by Utilizing Side Information on OFDM Sparse Channel Estimation
The second generation of digital video broadcasting (DVB-T2) standard utilizes orthogonal frequency division multiplexing (OFDM) system to reduce and to compensate the channel effects by utilizing its estimation. Since wireless channels are inherently sparse, it is possible to utilize sparse representation (SR) methods to estimate the channel. In addition to sparsity feature of the channel, the...
