Wireless communication systems are expected to provide higher transmission rates and better quality of servicein emerging wireless systems. However, there are various challenges that wireless systems face such as theharsh wireless channels and the limited spectrum. Thus, novel techniques are required to deal with suchchallenges.Efficient modulation techniques are essential in facilitating the provision of high transmission rates and betterquality of service. Nevertheless, traditional modulation techniques (e.g., quadrature amplitude modulation andphase shift keying) suffer from serious problems when they are used over wireless channels with multipathfading, inter-symbol interference and phase noise. Therefore, there is a growing need for novel modulationtechniques that can provide higher transmission rates and better quality of service over harsh wireless channels.DragonWave Inc. is seeking new & novel techniques in order to reach higher throughput capacities and higherspectral efficiency. Spectral efficiency is critical because of the general scarcity of spectrum suitable forbackhaul applications globally. In this project, we will explore non-traditional modulation schemes (e.g., spiralmodulation and optimally-designed constellation) for higher transmission rates and better quality of service inemerging wireless communication systems. We will test the suitability of these modulation schemes foremerging wireless communication systems and analyze their performance analytically, by simulation, and usingexperimental work. We will evaluate the performance of these algorithms in terms of the through gain,probability of error, outage probability, spectral efficiency (in bits/sec/Hz), and energy efficiency (bits/sec/Joul)under realistic channel conditions.
