regarding 8 channel polyphase filter bank

data_type = 'cosine';
for n=1:channels
if strcmp(data_type,'constant') // this strcmp compares two string if they will be identical then it will return
tx_data_in(n,1:data_len)=((1/n)-0.1) + j*0.1;  %setting complex to stop XFFT warnings
else
tx_data_in(n,1:data_len)=((1/n)-0.1).*exp(j.*(1/(channels*2*pi)).*n.*(1:1:data_len));

 

 

my question:

for generating input data why this channeliser.m file is using these two specific equation one is in if and other is in else

 

what kind of input it is generating .please explain.

thanks
