Performance analysis of a two dimensional spread spectrum multicarrier system in Rayleigh fading channel

1-dimensional spread spectrum (1DSS) technology is widely used nowadays, such as in the DS-CDMA system, while a new column-orthogonal two dimension spread spectrum technique (2D SS) is proposed in Youxi Tang [Proceeding of ICCCAS 2002]. In this paper, we describe this kind of two dimensional spread spectrum technique in detail and represent it strictly. Based on the 2D SS technique, we discuss the orthogonal multicarrier communication system under Rayleigh fading channel with an additive white Gaussian noise. A closed-form expression of the bit error rate performance of this communication system is derived. Numerical result of the performance of this 2D SS multicarrier system shows its advantage in low signal noise ratio.
