Hi,
I'm relatively new to Labview. So please excuse my 'naive' questions. I've made a Baseband OFDM Tx/Rx using LV 2009 and Modn toolkit. The steps I've used are interleaving, channel coding, mapping bits to symbols and then IFFT (omitted the Cyclic Prefix part as of now). The receiver is designed in a similar manner. I used 128 bit PN sequence initailly as the source. But now I've managed to convert a JPG into a bitstream for further modulation. I think my VI is making only one OFDM symbol and I'm presently having no control over the number of carriers used.
I'm posting the VI over here. I would like help in a few things
1. How do I control the number of carriers say 128,256,512 or 1024?
2. Even if I achieve this simullation how do I specify (and control) the carrier frequencies, guard band etc?
I do not have any Hardware as of now. I'm just implementing baseband OFDM Tx and Rx in the same VI. Planning to go about making a Tx and Rx separately using PXIe chassis and 5641 IFRIO cards. Any leads would be highly appreciated!
