System and method for mitigating memory requirements
First Claim
1. A receiver adapted to receive multi-protocol encapsulation forward error correction frame type application data and encoded error correction data, and to correct erroneous sections in said application data, comprising:
- an erasure structure list table for storing therein data relating to unreliable sections within the multi-protocol encapsulation forward error correction frame;
a data processing unit;
wherein said data processing unit is adapted to;
(i) accept an indication per erroneous section; and
(ii) cause said data relating to the unreliable sections to be stored in said erasure structure list table based on said indication(s); and
wherein the data contained in the erasure structure list table is utilized for performing handovers.

Abstract
A receiver is provided, which is adapted to receive MPE-FEC frames and to correct erroneous sections within a received MPE-FEC frame by detecting unreliable sections and storing in an erasure list (“ESL”) table compressed data that includes the base address of each detected erroneous section, together with the respective section'"'"'s size. The size of the ESL table may be fixed, or it may correlate, or dynamically change according to the actual number of detected erroneous sections. The data stored in the erasure list may then be forwarded to a decoder to correct erroneous sections. The erroneous sections may be detected by using CRC, and the decoder may be a Reed-Solomon decoder. If the application data table of the MPE-FEC is error-free (or full or errors), in which case the erasure structure list is empty (or full of errors), in which case the erasure structure list is empty (or full), this means that no FEC reception and error corrections are required, because there are no sections to correct in the first case and the decoder is incapable of correcting too many sections in the second case. Therefore, the receiving circuitry, or at least the decoder, may be disabled to save battery power.
