I am asking a doubt regarding
receiver using an Adalm Pluto SDR
In the receiver section we are using Polyphase
Clock Sync, Linear
Equalizer and Costas
Loop.
My doubt is that is the configuration parameters of these
blocks are dependent on the BW of the signal(Sample Rate)
Keeping the parameters as Normal (In
Polyphase Clock Sync block- No of
filters(nfilts) as 32, Loop Bw .0628, RRC filter as
firdes.root_raised_cosine(nfilts,
nfilts, 1.0/float(sps), 0.35, 11*sps*nfilts), sps as 4
; In
Linear Equalizer No of Taps as 15 ;In CostasLoop
Loop BW as .0628) when I set the BW(sample Rate around)1MHz I
can receive the datas.
But when I set the BW(Sample Rate) as
125KHz I cannot receive the datas.
Anyone plese tell me what
modification I have to make ?
