ABSTRACT
OFDM (Orthogonal Frequency Division Multiplexing) has been widely adopted for high data rate
wireless communication systems due to its advantages such as extraordinary spectral efficiency,
robustness to channel fading and better QoS (Quality of Service) performance for multiple users.
However, some challenging issues are still unresolved in OFDM systems. One of the issues is the high
PAPR (peak-toaverage power ratio), which results in nonlinearity in power amplifiers, and causes out
of band radiation and in band distortion. This paper reviews some conventional PAPR reduction
techniques and their modifications to achieve better PAPR performance. Advantages and
disadvantages of each technique are discussed in detail. And comparisons between different techniques
are also presented. Finally, this paper makes a prospect forecast about the direction for further
researches in the area of PAPR reduction for OFDM signals.

ABSTRACT
Network technologies are traditionally based on wireline solutions. But the introduction of the IEEE
802.11 standards have made a huge impact on the market such that laptops, PCs, printers, cellphones,
and VoIP phones, MP3 players in our homes, in offices and even in public areas have incorporated the
wireless LAN technology. Wireless broadband technologies nowadays provide unlimited broadband
access to users which were previously offered only to wireline users. In this paper, we review and
summarize one of the emerging wireless broadband technology i.e. IEEE 802.11,which is a set of
physical layer standard for implementing wireless local area network computer communication in the
2.4,3.6,5 and 60GHz frequency band. They fix technology issues or add functionality which is
expected to be required by future applications. Though some of the earlier versions of these
technologies are obsolete (such as HiperLAN) now but still we have included them in this review for
the sake of completeness.

PERFORMANCE COMPARISON OF PACKET SCHEDULING ALGORITHMS FOR
VIDEO TRAFFIC IN LTE CELLULAR NETWORK
Biswapratapsingh Sahoo, Indian Institute of Technology, India
ABSTRACT
In this paper we have studied downlink packet scheduling algorithms proposed for LTE cellular
networks. The study emphasize on three most promising scheduling algorithms such as: FLS, EXP
rule and LOG rule. The performance of these three algorithms is conducted over video traffic in a
vehicular environment using LTE-Sim simulator. The simulation was setup with varying number of
users from 10 - 60 in fixed bounded regions of 1 km radius. The main goal this study is to provide
results that will help in the design process of packet scheduler for LTE cellular networks, aiming to get
better overall performance users. Simulation results show that, the FLS scheme outperforms in terms
of average system throughput, average packet delay, PLR; and with a satisfactory level of fairness
index.

COMPARATIVE STUDY OF QOS PARAMETERS OF SIP PROTOCOL IN
802.11A AND 802.11B NETWORK
Sutanu Ghosh, Dr. Sudhir Chandra Sur Degree Engg College.,India.
ABSTRACT
Present day, the internet telephony growth is much faster than previous. Now we are familiar with
digitized packet of voice stream. So, we have required VOIP communication. SIP is one type of VOIP
protocol. This one has a SIP proxy. There have one of the important communication environment
Wireless LAN (WLAN). WLAN have different radio link standard. Here I am comparing SIP protocol
in two radio link standard 802.11a and 802.11b environment. The first one have maximum
transmission rate of 54Mbps and second one have maximum transmission rate of 11Mbps. In this
paper I want to show the results in a comparative plot. These comparisons include server /client
throughput, packet drops, end to end delay etc
