Abstract :
This paper presents the performance analysis of super-orthogonal space-frequency trellis coded OFDM (SOSFTC-OFDM) system using the Gauss-Chebyshev quadrature technique. SOSFTC-OFDM is a form of the super-orthogonal space-time trellis code that is used with OFDM. SOSFTC-OFDM utilizes the diversities in frequency and space domain by assuming that coding is done along adjacent subcarrier in an OFDM environment. This paper evaluates the exact pairwise error probability (PEP) of the SOSFTC-OFDM system based on the Gauss-Chebyshev quadrature formula and used the PEP to calculate the approximated average bit error probability. Comparing the calculated average bit error probability to the simulated our results shows 0.2 dB SNR deviation for 10-2 average bit error probability at error event of length 3.
