In this paper we propose a new design of LT codes, which decreases the amount of necessary overhead in comparison to existing designs. The design focuses on a parameter of the LT decoding process called the ripple size. This parameter was also a key element in the design proposed in the original work by Luby. Specifically, Luby argued that an LT code should provide a constant ripple size during decoding...
Practical digital communication systems are designed to operate well in typical conditions, where the bit/packet error rates are below a certain level. In packet-based systems, if Bob has a data to send to Alice then Bob first transmits a preamble/packet header followed by data. A necessary condition to receive the data correctly is to receive the packet header and therefore headers use a more robust...
