WIRELESS COMMUNICATION SYSTEM, DISTRIBUTION METHOD OF PILOT SIGNALS (VERSIONS) AND PILOT MODEL (VERSIONS)

摘要

FIELD: information technologies.;SUBSTANCE: method is applied for distribution of pilot signals for transmission of multiple pilot flows through system of antenna with multiple inputs-outputs (MIMO) with the use of modulation which is known as multiplexing with orthogonal frequency division (OFDM). In the version of invention implementation the distribution of pilot signals is applicable to structure of adjacent scenes, and two pilot signals are arranged for each pilot flow in structure of scenes, which includes 8 subcarriers and 6 OFDM symbols. The above 8 pilot flows are grouped in two clusters of pilot flows, and pilot signals for each cluster of pilot flows are grouped in two pilot clusters. Four pilot clusters are arranged in structure of the first scene, and arrangement of pilot clusters in structure of the second scene corresponds to arrangement in structure of the first scene. As a result, high transmission speed is reached in such wireless communication system.;EFFECT: higher transmission speed in antenna system with multiple inputs-outputs.;42 cl, 16 dwg
