Abstract :
RS code concatenated with PTCM technology and symbol interleaver are experimentally investigated in 60 GHz OFDM-RoF system. Symbol interleaver is used to combat the asymmetrical error distribution in OFDM sub-carriers, and RS with high code rate concatenated with PTCM can correct errors to improve performance of the OFDM system. Experimental results show that the receiver sensitivity of 2.5 Gb/s OFDM signal adopted the 16QAM modulation format with RS-PTCM scheme can save up to 7 dB receive power relative to 2.5 Gb/s OFDM signal with the uncoded QPSK scheme.
