METHODS AND MACHINES FOR STRING CREATION, AND METHODS AND MACHINES FOR STRING PROCESSING

Abstract

The invention's proposed solutions address the field of communication, specifically, the method of chaining, the chaining machine, the storage medium using computers, multi-purpose processors, and the communication system. The chaining method in the invention includes the following steps: multiplying a predefined ultra-high traffic long training chain (EHT LTF) with matrix p to obtain a matrix-mapped EHT LTF chain, where matrix p is a matrix η X n, and Π is greater than 8; and transmitting the matrix-mapped EHT LTF chain. According to the chaining method and machine proposed in the invention's solutions, the matrix-mapped EHT LTF chain in the Physical Layer Protocol Data Unit (PPDU) has a low peak-to-average power ratio (PAPR).
