Abstract
This work presents a performance analysis of linear-search high rate full diversity (HRFD)
for polarization division multiplexing coherent optical orthogonal frequency division
multiplexing (PDM-CO-OFDM) communication systems. The space-time block code (STBC)
is used to gain up signal to noise ratio (SNR). To achieve a high rate and full diversity,
a STBC code is provided -where it is orthogonal between the consequence times. The maximum
likelihood detection (MLD) is used. In addition, the number of searching for decoding is
dependent on only constellation sizes while the conventional scheme; ex. the Silver code,
its searching grows up exponentially. The proposed method is called high rate full diversity
STBC (HRFD-STBC). The system performance of the system is evaluated by numerical
simulation method. The results show that the bit error rate (BER) performance of the
proposed HRFD-STBC is slightly higher than the Silver Code. However, at the high
polarization dependent loss (PDL) channel, the BER of the STBC code is only a little higher
that the Silver Code.
