Hello all,
I am trying to implement OFDM transceiver on E310. Lastly, i already
implemented OFDM on N310 (in network mode connected to computer) using
GNURadio blocks. But when i run same example
(*ofdm_rx_tx_hier_blocks.grc)* on E310 it gives 'U' and 'O's. Processor
cannot handle incoming and outgoing data.
Then, i put OFDM transmit block to one E310 and OFDM receive to anther
to decrease load on processor. Again, transmitter gives 'U' and receiver
gives 'O's. Receiver also gives that info:
INFO: Detected an invalid packet at item
INFO: Parser returned #f
So, it cannot decode OFDM header. I guess packets are corrupted because
of bad transmission.
I know that, processor cannot handle that much data. I should go to FPGA
and RFNoC. But in here, available OFDM implementation in RFNoC using
GNURadio is not fit into FPGA (i can put 3 RFNoC blocks).
So should i implement my own OFDM implementation on FPGA?
Or, can you please suggest another way to implement OFDM Transceiver on
E310?
Best regards.
