Performance analysis of a novel OWDM-IDMA approach for wireless communication system

Efficiency and adaptivity play a major role in the design of fourth-generation wireless systems (4G). These systems should be efficient in terms of bandwidth and power allocation and will satisfy the users requirement on low power consumption, little interferences with other systems, and high rate transmission. Moreover, low complexity transceivers are expected. This paper will propose a novel multiple access technique called OWDM-IDMA (Orthogonal WavelengthDivision Multiplexing-Interleave Division Multiple Access) as the combination of the OWDM (Orthogonal Wavelength-Division Multiplexing) and IDMA (Interleave Division Multiple Access) schemes. The IDMA and OWDM principles are also outlined. The comparison between the conventional OFDM-IDMA and the proposed OWDM-IDMA is performed in term of Power to Average Power Ratio PAPR, as well as evaluating the performance of our presented technique over Additive White Gaussian Noise AWGN multipath channels by estimating the BER (Binary Error Rate).
