Abstract :
Existing rateless codes have low intermediate symbol recovery rates (ISRR). Therefore, we first design new rateless codes with close to optimal ISRR employing genetic algorithms. Next, we assume an estimate of the channel erasure rate is available and propose an algorithm to further improve the ISRR of the designed codes.
