 The LO of my LNB is 1998MHz. It means that when the dongle is tuned to 600MHz, it actually receives 600+1998Mhz!)
 
 LTE-Cell-Scanner decodes LTE MIB successfully in 1850-1880MHz band, but unsuccessful for other bands even they seems pretty like LTE 20MHz spectrum.

 Now TD-LTE signal is identified successfully, maybe adding TD-LTE support to LTE-Cell-Scanner is a good idea (Done! See: https://github.com/JiaoXianjun/LTE-Cell-Scanner).
 
 But now LTE-Cell-Scanner only works for situation where there isn't MMDS LNB, because LTE-Cell-Scanner assumes analytic relationship between carrier and sampling frequency.
-When there is external LNB, the relationship won't be maintained anymore. I offer a work around. A module sampling_ppm_f_search_set_by_pss.m is used to do 
-sampling frequency estimation and compensation. Thus LTE-Cell-Scanner can work only for uncertain carrier frequency (By setting k_factor to constant 1). By this way 
-the whole scanner drops analytic relationship between carrier and sampling frequency. See CellSearch.m for detailed informaiton.
