I am working on a project to be able to demodulate satellite radio using GNU Radio. The goal is to figure out what modulation is being used. It's not traditional DVB, but a hybrid of QPSK and OFDM modulation. The width of the carrier is 12.5Mhz. You need to show that you have experience doing GNU radio demodulations to win this project. I am not able to figure out how to do it myself so this is why I am posting the project. The carrier has each two-carrier group broadcast 100 8-kilobit-per-second streams in approximately 4 MHz of radio spectrum. These streams were combined using a patented process to form a variable number of channels using a variety of bitrates. Bandwidth is separated into segments of 4-kilobit-per-second virtual "streams" ...

Your project consists of simulating a DL OFDM signal assuming single port output (no MIMO). The signal consists of samples spaced Tc apart and using the NR number of subcarriers and subcarrier spacing as specified in TS 38.101-1 (FR1 range only, Table 5.3.2-1). To map the bit stream onto the complex QPSK, 16QAM and 64QAM symbols, use the mapping rules provided in TS 38.211, sections 5.1.3, 5.1.4 and 5.1.5 (no Matlab direct mapping should be used). The generated signal, represented by the IFFT, is a baseband signal; you do not need to upconvert it.
