Summary: | PROBLEM TO BE SOLVED: To realize improvement of noise resistance along with improvement of transmission rate in the next-generation terrestrial digital broadcasting transmission system.SOLUTION: A transmitter 1 includes: a mapping unit 11a/11b configured to map hierarchical data to a data carrier. According to a table corresponding to a type of a carrier modulation scheme, the mapping unit 11a/11b are configured to determine an arrangement on an I axis and an arrangement on a Q axis of each signal point.SELECTED DRAWING: Figure 2
【課題】次世代の地上デジタル放送伝送方式において、伝送レートの向上と共に雑音耐性の向上を実現すること。【解決手段】本発明に係る送信装置1は、階層データをデータキャリアにマッピングするように構成されているマッピング部11a/11bを具備しており、マッピング部11a/11bは、キャリア変調方式の種類に対応するテーブルに従って、各信号点のI軸上の配置及びQ軸上の配置を決定するように構成されている。【選択図】図2 |
