Re: [Discuss-gnuradio] Adding Attenuation in GNU radio

Ah, yeah, in that case, a power path loss of 80 dB is equivalent to an amplitude multiplication by 10^-4. Best regards, Marcus On 07/17/2017 12:17 AM, Jose Ruvalcaba wrote: Hi Marcus, Thanks for your response. I'm trying to make a channel simulator where my signal going into the USRP gets

Re: [Discuss-gnuradio] Adding Attenuation in GNU radio

You can also check out the channel model block in GRC, there's also several other useful blocks under the imparements category that may be useful for modeling different kinds of environments like multipath or doppler. On Jul 16, 2017 6:20 PM, "Jose Ruvalcaba" wrote: > Hi

Re: [Discuss-gnuradio] Adding Attenuation in GNU radio

Hi Marcus, Thanks for your response. I'm trying to make a channel simulator where my signal going into the USRP gets attenuated by free space path loss. Typically, I know that this is done through the use of hardware, like fixed attenuators, but I wanted to go into an all DSP approach with the

Re: [Discuss-gnuradio] Adding Attenuation in GNU radio

Hi Jose, yep, multiply const with a real value |·| < 1 would be **equivalent** to an analog attenuator. anyway, it's very uncommon to do such an operation in DSP, unless you need a fair comparison between different signals or such. Maybe you'd want to explain why you want to do that? Best

[Discuss-gnuradio] Adding Attenuation in GNU radio

Hello, This may seem like a really simple question, but If I wanted to attenuate my signal coming out from a USRP source block in GRC, say by 80 dB,, how would I go ahead and do that? Would I just add a multiply constant block after my USRP source block to scale down the incoming signal's
