Abstract
Forward error correction (FEC) enables the receiver to detect and correct error in a packet. The fountain code, which is a subclass of FEC, is a linear code to have high scalability and low complexities, and the Luby transform (LT) code is the first practical fountain code. In this letter, we propose a new broadcast method to increase the reliability of broadcast data transfer using the LT code. The proposed method enhances the reliability of the broadcast using the LT code by adjusting the number of output packets depending on a target probability. We develop a new analytic model to derive the data restoration probability with given configuration of encoding and decoding process.
