OFDM demodulator with communication channel effects¶
Assignment 03
OFDM symbol is transmitted through a communication channel of unknown characteristics, the same way as was done in the OFDM signal generator Basic Level example. Input files contain time-domain I/Q samples of the received signal in floating-point format. Your task is to decode the received information.
The obtained bitstream represents ASCII-coded characters (8 bits per character), each character stored with its most significant bit (MSB) first. As an output, your solution must generate a file receivedMessage.txt with the decoded text message.
Input Files¶
Source files in 03_ofdm_channelest.zip
- I_samples.csv
- Contains in-phase samples in floating point format (%1.6f).
- Q_samples.csv
- Contains quadrature-phase samples in floating point format (%1.6f).
Evaluation and Grading¶
The received text message must be identical to the one constructed on the transmitting end.
