We are designing a raised cosine filter in Matlab. I have developed most of the logic for BPSK Transmitter but I could use a little help with finishing it out. Not really sure how to plot this in stem or in scatterplot.
close all; clear all;% Design BPSK transmitter with the random data bits.
M = 5; % Modulation levels (Binary PSK)
k = log2(M); % number of bits per symbol
N = 2e3; % total number of random bits
sps = 4; % number of samples per symbol
EbN0 = 10; % Eb/N0 level in dB
iBits = rand(N, 1) > 0.5; % generate random bits
bits = 2*iBits - 1; % convert modulation symbols
% plot first fifty bits.
figure;stem( ); grid on; title('Random bits'); xlabel('samples'); ylabel('amplitude');% Attach the plot here…
% plot constellation diagram
scatterplot( ,1,0,'*r');grid on; % Attach the plot here…
