Abstract :
This paper presents a channel coding scheme for OFDM with 64-QAM and 256-QAM over Rayleigh channel. In our proposed scheme, the OFDM system employs three mode of IFFT with 4k, 16k, and 32k. In addition, the concatenated coding scheme of LDPC and BCH code is utilized as channel code referring to the standard from ETSI EN 302 755. Aside from the simulation, we also measure the system performance via the instrument that using DVB-T2 transmitter and receiver. Finally, the comparison and discussion of the simulation and trial measurement are demonstrated.
