Abstract

In this paper we present an extension of our previous investigation [1] of the effect of environmental temperature variation on the bit error rate (BER) performance of multiwavelength 2- dimensional wavelength hopping time spreading optical code division multiple access (2D-WH/TS OCDMA) signals that utilises picosecond pulses for code formation. Using equations already derived in [1] for modelling the effects of temperature variation on autocorrelation signal resulting from the decoding of an incoherent 2D-WH/TS OCDMA encoded signal which consists of w wavelength pulses each having a pulsewidth of τ after propagating in L (Km) of fibre, we arrive at the expression for the envelope of the resulting autocorrelation peak St.
