Abstract
Put forward the compression of frequency sub-carrier in order to increase the frequency resource. The invention had experienced system simulation
lab test
and out door test
and had been testified that 1.4MHz band of sub-carrier is feasible the thought of the invention is adjustment of sub-carrier band in order to increase the frequency efficiency and to decrease the same frequency interference. The invention is also used to increase the capability of TD-SCDMA-SCMDA network.
