Problems solved by technology

However, under current replication schemes, this tends to result in increased PAPR, which results in more signal distortion and thus requires the transmitter to reduce the average transmit power in order to reduce the peak power of the transmitted signal

Abstract

The invention provides a wireless communication method and device. The method includes the steps: generating dual carrier modulation (DCM) encoded data in a first half of a full signal bandwidth; copying the DCM encoded data generated in the first half of the full signal bandwidth in the second half of the full signal bandwidth; and multiplying the DCM encoded data replicated in the second half of the full signal bandwidth by a modulation vector. According to the invention, the peak-to-average power ratio (PAPR) of the BPSK in EHT transmission can be obviously reduced.

Description

technical field [0001] The present invention relates to wireless communications, and more particularly to dual-carrier duplication for binary phase-shift keying (BPSK) in wireless communications with low peak-to-average power ratio (PAPR) repetition Modulation (duplicated dual carrier modulation). Background technique [0002] Unless otherwise indicated herein, the approaches described in this section are not prior art to the claims and are not admitted to be prior art by inclusion in this section. [0003] In wireless communication performed in wireless local area networks (WLANs) based on Institute of Electrical and Electronics Engineers (Institute of Electrical and Electronics Engineers, IEEE) 802.11 standards (such as IEEE 802.11ax and IEEE 802.11be), BPSK pairs can be used. Data is encoded and modulated using dual carrier modulation (DCM) for transmission on two subcarriers. In the specification of IEEE 802.11be, a duplication (duplication) scheme is further defined o...
