Embedded system is the speciality computer system, which the hardware and the application software are united. Because of the embedded system's outstanding characteristics of small size, high performance, low cost, and well practicality, it has been applied in many fields such as communication, industrial control. Embedded system has large market prospect. In this design, an embedded industry control system's hardware and software platform was designed based on S3C2410(arm9 core) and embedded linux. According to the requirements of industrial controllers, embedded linux operating system was used, and the embedded linux which has been explanted to the hardware platform. And the information collection server and remote monitoring client were designed. The test results show the function and the design of Embedded Industry Controller are feasible. Such as the system is running on the ARM linux platform，the web server，the function modules of the hardware platform run in good working states. It reaches the expected design goals.

The advantages and disadvantages of the previous predistortion methods for high power amplifiers (HPA) in orthogonal frequency division multiplexing (OFDM) transmitter were compared and summarized systematically. Block-oriented model-based adaptive digital predistortion technique was presented to compensate for the distortions in HPA with memory. The proposed predistortion schemes were explained, where the adaptive predistorters of HPA with memory were constructed based on Wiener model, Hammerstein model and Wiener-Hammerstein model, respectively. Thus, the complexity of the model parameters of all aspects of Wiener-Hammerstein estimated is avoided, separately. This makes the predistortion design of a high power amplifier with memory became simple.
