Abstract
Data to be transmitted is converted into symbols using a plurality of data-to-symbol conversion processes. The symbols from these processes are then time-division multiplexed. Advantageously, at least one of these conversion processes incorporate coding in a manner which provides the same degree of error protection for each process. In the disclosed embodiments, the data originates from two independent sources and the data from each source is converted into symbols using a different data-to-symbol conversion process.
