Increased channel capacity of optical transmission system is obtained either by increasing the bit rate of transmission or by using the technique of wavelength division multiplexing (WDM). In long distance communication, higher launched power is required to achieve the required signal to noise ratio. But with the increased launched optical powers, bit rates and the number of wavelength channels, the...
In this paper, a numerical method is presented to evaluate the bit error rate (BER) of different Orthogonal Space-Time Block Codes (OSTBCs) over Rayleigh fading channel for different transmission bit rate. The comparisons of Orthogonal Space-Time Block Codes are made with the equivalent uncoded Single-Input Single-Output (SISO) channel and uncoded space diversity. The result shows that a full rate...
