Abstract:
1. A method for encoding data in a data encoder, the method comprising the steps of: receiving data at the input of the data encoder; encoding a first portion of the received data using a first encoding process, the first portion of received data for reception by a first type of receiver, the first encoded data including systematic packets representing the first portion of the received data and non-systematic packets generated by encoding the first portion, the first encoding process using a Galois Field generator matrix to supplement the data; inserting training data into the first encoded data; combining the first encoded data and training data into a second portion of the received data, the second portion not being encoded using a first encoding process, the second portion of the received data for reception by a second type of receiver, wherein the second type of receiver is not capable of decoding the first encoded data; and encoding the combined data using a trellis encoding process, the trellis encoding process being the same for all the combined data.
