Abstract
Filter bank multicarrier communications (FBMC) have recently gained popularity in both wired and wireless communications and this is mostly due to superior flexibility, increased spectral efficiency and better spectral containment when compared to traditional OFDM systems. A particular version of FBMC known as FBMC-IOTA, consists of an isotropic orthogonal transform algorithm (IOTA) pulse adapted
OFDM modulated with Offset-QAM symbols and this is the focus of our study.
This thesis is an industrial project in collaboration with Aeroflex, it reviews the state of the art in the
Long Term Evolution LTE communications, then goes further to discuss the important features of next generation networks (NGN) and its related physical layer PHY requirements. The primary focus of this thesis was to evaluate how channel estimation techniques for OFDM systems used in LTE-Advanced work, implement the existing channel estimation techniques in FBMC-IOTA systems and provide a comparative performance analysis in terms of bit error rate performance, using OFDM as a benchmark.
The performance of ideal, preamble-based and pilot-based channel estimation methods have been simulated in MATLAB with AWGN, SUI-3 and IEEE 802.11 channel models in OFDM and FBMCIOTA systems. The progress made in this thesis supports the FBMC as a promising waveform technique for the air interface of future 5G radio systems.

    Comparison and Analysis of Channel Estimation Algorithms in Ofdm Systems

    Abstract—The channel estimation can be performed for analyzing effect of channel on signal by either inserting pilot tones into all of the subcarriers of OFDM symbols with a specific period or inserting pilot tones into each OFDM symbol. The block type pilot channel estimation has been developed under the assumption of slow fading channel. When the data is transmitted at high bit rates, the channel impulse response can extend over many symbol periods, it leads to inter symbol interference. Orthogonal Frequency Division Multiplexing is one of the promising candidate to mitigate the ISI. This work improved various channel performance measures based on the comparison of various channel estimation algorithms and suggest a new technique which provides better performance. Keywords-OFDM, Block Pilot symbols, Channel estimation, Linear minimum mean square error (LMMSE), Mean square error (MSE), Bit error rate (BER)…

    Ofdm

    I. I NTRODUCTION The American IEEE802.11a standard and the European equivalent HIPERLAN/2 are two similar concepts for broadband wireless LANs (WLAN) in the 5 GHz band. Both standards are based on the multicarrier modulation technique OFDM (orthogonal frequency division multiplexing) combined with convolutional channel coding. The baseband modulation schemes of both standards are very similar, which simplifies implementation considerably. Challanges and difficulties considered in this paper regard both systems. Except for slight differences in signal mapping, most discrepancies between the standards regard the higher protocol layers. Section II presents some fundamentals of OFDM and the WLAN standards. Here we focus on the baseband modulation in the PHY layer and explain parts of the PHY burst structure relevant to channel estimation. Section III describes a frequency domain channel estimator. Assuming channel impulse responses being…

    3g Wireless Network

    Abstract: In today’s era, it is the need of hour to get ourselves acquaint with the communication technology, its tools and trends. Mobile communication is an important technology in this regard and mobile phone has become the most common tool of communication over the recent years. As several innovative improvements regarding mobile communication technologies have been made by developing various multiple-access schemes. But a big challenge is to select the right technology for the applications and systematically identify the factors that influence the overall performance. In this paper work, we have divided the work into two groups. The first group tells about the 3G and its features and the second group present the detail comparison between third and fourth generations of the mobile communication technologies in a paragraph form to have a better knowledge and understanding in the advancement of mobile communication systems. The work presented here will be helpful for designing the new techniques for the development of higher generation mobile communication systems. This work can let all those learners who are trying to enhance their curiosity in the field of mobile communication system.…
