anyone can tell me the code,thanks

actual_time_offset=m*.005*k_factor; // i don't know what is this means ????????

for (uint8 t=0;t<3;t++) {
for (uint16 idx=0;idx<9600;idx++) {
xc_incoherent_single[t][idx][foi]=0;
}
for (uint16 m=0;m<n_comb_xc;m++) {
// Because of the large supported frequency offsets and the large
// amount of time represented by the capture buffer, the length
// in samples, of a frame varies by the frequency offset.
//double actual_time_offset=m*.005k_factor;
**//double actual_start_index=itpp::round_i(actual_time_offsetFS_LTE/16);
double actual_start_index=itpp::round_i(m*.005k_factorfs_programmed);**
for (uint16 idx=0;idx<9600;idx++) {
xc_incoherent_single[t][idx][foi]+=sqr(xc[t][idx+actual_start_index][foi]);
}
