Re: [DPRG] Wireless Protocols
- There are several these; one is Manchester encoding, which uses two bits
to encode each bit of data (100% overhead), and guarantees no more than
two ones or zeros in a row; there are others that use 12 bits to encode
each 8-bit byte, and guarantee no more than 4 ones or zeros in a row. I
think these might be primarily useful if your receiver incorporates a
"bit slicer" to resolve incoming data.
Anyway, someone recently pointed me to some good application notes at
RFM. They are somewhat oriented toward RFM's products, but there's a
lot of good general info:
In particular, these talk about encoding/decoding schemes and balanced
Hope this helps,
