Description

technical field

[0001] The invention relates to secure communication, in particular to a 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 transmission.
