[Discuss-gnuradio] measure the impulse response of the channel

[峰周]

Hi all,
I am new on GNU Radio.I want to measure the impulse response of the
channel.
I transmit a known m-sequence using BPSK modulation(dbpsk.py)at 2.4G,
USRP1.

At the receiver set, where should I cross-correlate the received signal
with the known m-sequence to give the (complex) impulse response of the
channel?

Since I don't need to probe the channel at the Rx continuously , I think
the gr-sounder is not suitable.

Thanks
