鑑於多載波系統相對於單一載波系統，擁有較大的頻寬效益、較高的資料傳輸率等優點，因而被廣泛的使用在各系統中。例如在無線通訊方面的窄頻個人通訊服務（PCS）的應用和多載波碼分多工（MC-CDMA）系統等。
本論文主要是設計規劃多載波調變訊號的接收系統，提供整個接收系統的動作流程以及程式流程，並針對其中控制模組、偵測驗證模組與頻率估測模組等三方面深入研究探討，詳細說明其設計原理並評估其效能。
論文中，並針對全系統的整合有詳細的描述和測試，其中主要是採用SPW、Matlab以及C程式等方式來達成整個系統從模擬到整合到實現的系統工作需求；同時，亦探討系統中眾多參數值對系統效能的影響，以求能提高系統效能。
The multi-carrier system has better spectrum efficiency and higher data rate than a single-carrier system, therefore it uses in popular. For example, the application of narrow-band personal communication services (PCS) which uses in wireless communication and the system of multi-carrier code division multiple access (MC-CDMA) are using this technology for transmission.
This thesis discusses the design and implementation of a receiver for multi-tone signals. We offer the operating procedures and programming flowcharts to the receiving system. Then we design the system model which contains control module, signal-detected module and frequency-estimated module. In addition, we give a detailed description of the design ways and evaluate the performance of this system.
This thesis has a detailed description and experiment about the entire system. We use the SPW, Matlab and C program to achieve the requirement of system simulation and implementation. Simultaneously, we investigate the influence of several parameters in order to acquiring high system performance and find a method to improve it.
