Hi all, I'm trying to implement a low pass filter on a microcontroller, getting coefficients in MATLAB. I have the transfer function in s-domain, so I am using bilinear() to get the coefficients. This gives num and den (a and b coefficients) for an IIR implementation. I would like to know if it possible to get the coefficients for an FIR implementation of a filter, when you have the transf...

Well I had a similar challenge with the decision region but not any more. From you code, what you need to do is, when you work out the decision angles (phases)from 0 to pi (anti-clockwise on the constellation), its positive but from 0 to -pi (clockwise) the phases used should be negative. Also take into account the wrap around regions and take decisions seperately for it. Check below to have a bet...

Does anyone know of a way to reduce this code and still achieve gray mapping, because when M (in MPSK) gets higher, gray mapping using the method I used below will be too lenghty. Thanks clear all clc M=8; N=1200; data=rand(1,N)> 0.5; Mpsk_symbol=zeros(1,length(data)/3); for n=1:length(data)/3 p1=data(3*n-2); p2=data(3*n-1); p3=data(3*n); if p1==0 && p2==0 && p3==1
Sampling frequency offset correction & estimation Speth et al.

Hello everyone, I'm having troubles with SFO estimation and its correction on Speth algorithm, since I don't get correct estimated values neither in AWGN nor in ideal case. Basically, I add SFO to OFDM signal through interpolation in time domain. Then trying to estimate with following code: temp_pilots_rx=[pos_pilot_symbols_rx_neg; 0; pos_pilot_symbols_rx_pos;]; % separate negative & positi...
Halfband and FIR filter for decimation

Hi, I want to design a decimation filter for a Sigma-Delta modulator. The modulator input is 20Khz sinus signal. And this signal is oversampled to 2.5Mhz. So decimation ratio is about 64. First I designed a CIC filter which has a decimation ratio of 16. After a halfband filter and an FIR filter. So halfband filter output is 80 Khz, FIR filter output is 40 khz. Anyway, I want to design halfband ...
