#1 some questions about code

GANESH YELLAPU — Wed, 25 Jul 2018 09:36:14 -0000

Hi,

In the example.c, erasure locations are added to the array erasures[nerasures++].
However erasures are not filled in the codeword[] before calculating the syndrome (inside decode_data())

In particular, the function byte_erasure() is not called to initialize the erasures in the codeword[].

kindly clear me in this regard.

Thank you,

Ganesh Yellapu

any porting with RFC-2733? (details inside)

Hi,

Do u have any porting with RFC-2733 or RFC-3119?

As to real-time multimedia (say, mp3 streams)
transmission via wireless environment (e.g. 802.11b
WLAN), ARQ is not suitable in that retransmission via
WLAN generates delay which will greatly decrease the
performance of real-time multimedia transmission. So
FEC should be the best choise to deal with lost packets.

Have you have ideas about porting Reed-Solomon codecs
with RFC-2733 or RFC-3119?

Or do you know any open source project related with
lost packet recovery in WLAN?

some questions about code

usually when one talk about RS codes they use terms
like codes of (255,249) or (7,5,3) etc...

You use NPAR (meaning number of parity bits) how does
that translate into the formats above?

was there a specific reason why you used NPAR rather
than taking the normal RS code paramters?
