What's missing:
* CRC16-CCITT to be computed over odd number of bits like 60 or 124
(all common implementations assume you encode integral # of bytes) [zecke]
Besides feeling stupid. I am done with this.
* decoding:
* decoder for the RM(30,14) code [zecke]
I am on this now. I also have my Check Matrix but there is another way to
decide how to correct the error but my books are not very clear on that... I
think I will complete this tomorrow.
* soft-input/soft-decision viterbi for the RCPC code
I assume you are on this now. Should I go for code to decode sysinfo/sync_pdu
based on type3 bits?
* synchronizer, able to detect synchro and normal
training sequence [laforge]
Once those tasks are completed, we can not only generate simulated burst bit
patterns, but also decode them - which should be a good start for the time
when Hopscotch' demodulator will spit out some real received bitstream.
