Abstract

The idea of this thesis work is to analyze the performance of a Wireless LAN systems employing IEEE 802.11 b standard. IEEE 802.11 b standard is an advanced version of the widely known 802.11 standard. There are 3 basic transmission techniques: Frequency Hopping Spread Spectrum or FHSS, Direct Sequence Spread Spectrum or DSSS Infrared. The 802.11 b standard was introduced after the 802.11 standard to define 2 different modulation techniques in addition to the two originally defined in the 802.11 standard. It supports higher data rates than its predecessor-5.5 and 11 Mbps. The new modulation techniques used are CCK-Complimentary coding and PBCC-Packet Binary Convolutional Coding. In this thesis, the entire functioning of a transmitter and receiver has been implemented using ivIA TLAB. The scenano that has been analyzed is simultaneous multiple channel transmission. A new technique has been introduced to enhance the performance of the existing system. The proposed technique will allow extra channels to be simultaneous operational with reduced probability of error. The analysis centers around finding out the maximum strain that the system can handle and what changes could be effected to maximize the performance of the system.
