- OFDM_SIM.m -- The main function.
- ofdm_parameters.m -- Configure some simulation parameters which includes some key ones as below
-
ifft_size
, IFFT/FFT size -
carrier_count
, sub carrier numbers -
symb_size
, modulation constellation mapping bit size, it relats to modulation scheme such as BPSK, QPSK, 16QPSK and 256PSK -
clipping
, OFDM amplitude clipping factor -
SNR_dB
, SNR with dB as unit -
guard_time
, guard time for between symbols -
spacing
, data subcarrier spacing
-
The image transmission quality is highly related to clipping/SNR/modulation scheme, so I simulate the system with different values of the above parameters. Here is some part of simulation result.
The project is created for OFDM simulation.
We transfer an image via the wireless system and test the performance of image transportation quality with different parameters. Furthur to explore the project.
