gps - Reading RF logged into the MATLAB and extract correct data from it

Question

I try to read an Rf logged data into the MATLAB, the format of this file is .LS3W and it read in matlab as file by following codes:

precision = 'uint8';
log_path = 'C:log_path';
log_name = 'LabSat-1bitquant.LS3W';
fid = fopen([log_path, '', log_name], 'r');
data = fread(fid, precision);
fclose(fid);

this data collection includes the GPS L1 band with 15MSPS@1bit, 2bits, and 3bits I/Q sampling rate. In this case, the following GPS L1 signals are detected with the PRN 1, 3, 8, 11, 14, 17, 18, 19, 22, 23, 31, and 32.

now my question is, how can I extract available data from the source file. for example, how can I extract and split Samples to I and Q element and plot them.
