my_bi2de(b, msbflag) now i need to convert bit vector into decimal numbers. so my_bi2de is the
my_de2bi(d, msbflag, n) This is the function to convert decimal to binary. here b is the binary
my_pskdemod(y , m) this function demodulate the psk modulated signal, here y is the modulated
my_pskmod(x , m) this is function for generating the phase shift keying modulation, where x
my_rrc(fd, fs, beta, delay) MY_RRC Produces the impulse response of a root raised cosine filter
my_rrcosflt(x, fd, fs, beta, ... MY_RRCOSFLT Filter the input signal using a root raised cosine filter.
my_speech(M, type_of_mod, fc,... here i am going to test my speech through various QAM, and PSK mod-demod
scatter_plot(m, type_of_mod, ... this program is to test the QAM and PSK modulation and demodulation
