Appeal No. 1997-2380
Application No. 08/121,809
The method and apparatus uses a first bit correction threshold
until the number of consecutive erasures of bad frames equals
six (Figure 5). Thereafter, the method and apparatus uses a
second bit correction threshold until the number of
consecutive frames that are not erased equals two. If two
good frames are received, then the method and apparatus
switches back to the first bit correction threshold.
Claim 1 is illustrative of the claimed invention, and it
reads as follows:
1. A method of determining whether frames of information
are bad or good frames of information based on multiple
thresholds in a communication system, the method comprising
the steps of:
determining whether a frame of information is a bad or
good frame of information based on a first bit correction
threshold;
erasing at least one frame of information determined to
be a bad frame of information; and
determining whether a frame of information is a bad or
good frame of information based on a second bit correction
threshold.
