INTERLEAVER MEMORY ALLOCATION METHOD AND APPARATUS

摘要

A first communication device estimates upstream channel conditions for an upstream channel and determines an upstream memory requirement for a first buffer at a second communication device and a first buffer at the first communication device based on the upstream channel conditions. A downstream memory requirement is received from the second communication device for a second buffer at the first communication device and a second buffer at the second communication device based on downstream channel conditions estimated at the second communication device for a downstream channel. The first communication device determines whether the sum of the upstream and downstream memory requirements exceeds an available amount of memory for implementing the first and second buffers at the first communication device and revises at least one of the memory requirements if the sum of the upstream and downstream memory requirements is different than the available amount of memory.
