A RECEIVER, DE-INTERLEAVING MEANS AND A METHOD FOR A REDUCED TIME DE-INTERLEAVING MEMORY

摘要

The invention provides a DAB receiver in which a reduced time de-interleaving memory for storing metrics is used, but which still allows processing of DAB services which normally would exceed the storage capacity of the memory. This is achieved by varying the length of a stored metric, depending upon the storage capacity required, by varying the number of stored reliability bits in a metric. In this way a trade-off can be made between storage capacity and processing quality.
