Chuck,
After taking a look at the 0.9 code (atsc_rx.cc), it looks like we were
instantiating atsci_equalizer_lms.
atsci_equalizer_lms uses a single FIR filter.

Unfortunately, all the repeaters around here have a 1240MHz input and
10.470GHz output, so dbrx on its own won't help (unless I will be lucky
enough to be in the uplink beam of a ham while transmitting :-) ). I am
already working on a receiving system based on an offset dish and modified
satell
The first method looks interesting, the only problem I find with it is that
I cannot tell wether what I am getting from the channel is noise or noise
plus some weak signal I cannot identify as such. When it comes to very busy
channels (eg on APRS frequency, you have signals almost all of the tim

I believe that most ATV is AM (almost 12 MHz) instead of VSB (6 MHz).

Hi all,
I still have problems receiving any data packets from my MICA2 Mote at ISM
band 433 MHz. I have tuned the usrp to the right frequency and designed the
channel filters and uspr_fft_py shows me nice results. On the other side I
changed the gmsk_test.py file in gnuradio-examples to my need
How do you declare two inputs of different data types?
Several atsc blocks pass a stream of 'float' and also 'syminfo'
(a struct of 4 ints).

but only of the same type(?).

I think you mean FM-ATV, mainkly used at 23 cm. which has a bandwidth of
Hello, I would like to write some code to calculate the SNR of a signal;

First you need to define SNR. If you measure the noise power of the
background within the passband when there is no sig

Is there anything ready for use or has anyone good suggestions to
implement this?
thanks
