[Discuss-gnuradio] OFDM_TX_RX

[farid mihoub]

Hello,

 

In the OFDM_tx, rx examples in gr-digital :

1- Why just a low level of noise affect the transmission and cause it to  stop.

2- in the the Tx output and the Rx input no matter the value of the multiply constant we apply

   that would not affect our transmission.

3- Is there any way to separate channel estimation and tracking from

   data transmission, sometime I get the error "invalid packet detected!" form the packet parser, also I need my data to bypass FEC and QAM.

   My purpose is to stream raw complex data to the I/Q components directly.

 

 

Thank you.
