Abstract

The present invention provides an LTE-based multicarrier modulation system, which adopts two-stage multicarrier modulation and demodulation. The LTE-based multicarrier modulation system has the beneficial technical effects that the frequency spectrum efficiency and the data transmissibility of an LTE system are guaranteed, the secrecy performance is greatly enhanced, and hardware costs and realization difficulties are reduced.

Description

technical field [0001] The present invention relates to secure communication, in particular to an LTE-based multi-carrier modulation system. Background technique [0002] In the future mobile communication system, high-bandwidth and high-speed data services are essential, which requires wireless communication technology to effectively eliminate the adverse effects of wireless channel fading on transmission, and achieve higher spectral efficiency. Take into account the equality among users. [0003] LTE (Long Term Evolution) is a long-term evolution of the UMTS (Universal Mobile Telecommunications System) technical standard formulated by 3GPP (Third Generation Partnership Project). The LTE system introduces key transmission technologies such as OFDM and MIMO, which significantly increases the spectrum efficiency and data transmission rate; and in order to obtain diversity multiplexing gain, the LTE system gradually adopts multi-carrier and dynamic modulation technologies for...
