This study purposed a low cost data acquisition system based on PIC32MX460F512L microcontrollers for Remote Data Acquisition System (RDAQ) like wind energy where moderate accuracy is required. Data acquisition is performed by inbuilt ten bits ADC converter of the microcontroller. Time mechanism is provided by in built Real Time Clock (RTC). An ENC28J60 Ethernet controller is used for interfacing with Internet network. This system also stores data in USB flash drive for backup data to increase reliability of system.

Forward Error Correction (FEC) is a developed system of error control applied in data transmission. It is often applied in a kind of system that is difficult and costly to build a reverse channel for the receiver to detect and correct data error. The following pages includes the basic function and background theory of FEC and some examples of FEC codes. We also represent some research findings on the application in Internet and wireless data transmission. Furthermore, in the last few paragraphs we bring forward the information of FEC's lately development.
