METHOD AND APPARATUS FOR PUNCTURING WITH UNEQUAL ERROR PROTECTION IN A WIRELESS COMMUNICATION SYSTEM |
摘要 |
A method and corresponding codec for (channel) encoding speech or other data bits for transmission via a wireless communication channel, the method providing unequal error protection (UEP) using only a single encoder, and including: a step (51e) of determining how many bits to puncture in each of typically two protection classes (C<A#191 C?B#191) so as to achieve either a predetermined or iterated desired level of error protection; and a step (52) of identifying which bits to puncture for each class so as to provide relatively strong and uniform protection for all bits in the first class (C?A#191), but protection that decreases in the same manner as the subjective importance decreases from the beginning to the end of the other classes. The method also accounts for so-called soft puncturing by modulators transmitting multiple bits per symbol with weaker protection for some of the bits of each symbol.
