Abstract:
(EN) In a transmitter apparatus for multicarrier-modulating symbols, each of which is a basic unit of digital signals, and transmitting the modulated symbols, the tolerance to interferences among the symbols can be improved, with little degradation of transmission efficiency in communication, by causing subcarriers each obtained by disposing a symbol in a first multicarrier symbol having a first guard interval and subcarriers each obtained by disposing a symbol in a second multicarrier symbol having a second guard interval longer than the first guard interval to be scattered among a plurality of subcarriers constituting a multicarrier at the same time.
(FR) L'invention concerne un appareil émetteur destiné à assurer la modulation multi- de symboles dont chacun est une unité de base de signaux numériques, et à émettre les symboles modulés. L'invention permet d'améliorer la tolérance aux interférences entre les symboles, tout en limitant la dégradation du rendement d'émission en cours de communication, en faisant en sorte que des sous-porteuses dont chacune est obtenue en disposant un symbole dans un premier symbole multi- présentant un premier intervalle de garde, et des sous-porteuses dont chacune est obtenue en disposant un symbole dans un deuxième symbole multi- présentant un deuxième intervalle de garde plus long que le premier intervalle de garde, soient dispersées en même temps parmi une pluralité de sous-porteuses constituant un ensemble multi-.
(JA)  デジタル信号の基本単位であるシンボルをマルチキャリア変調して送信する送信装置において、第1のガードインターバルを有する第1のマルチキャリアシンボル中でシンボルが配置されたサブキャリアと、第1のガードインターバルよりも長い第2のガードインターバルを有する第2のマルチキャリアシンボル中でシンボルが配置されたサブキャリアとが、同一時刻においてマルチキャリアを構成する複数のサブキャリアの間で散在していることで、通信の伝送効率をほとんど低下させることなく、シンボル間干渉に対する耐性を向上させる。
