Abstract :
Amongst the advantages of Multicarrier on-off keying (MOOK) is the simplicity of its transmitter-receiver pair and inherent good performance in noisy channels which make it a popular choice for some communication systems. However the MOOK technique is widely considered as bandwidth inefficient relative to other existing transmission schemes. The aim of this paper is to investigate methods for improving the spectral efficiency of this technique. Two strategies are proposed and analysed here. The methods investigated show that significant bandwidth efficiency enhancement can be achieved especially when the number of subcarriers is large.
