The R900 decoder is more CPU intensive because it requires three separate matched filters in order to decode all of the symbols the protocol's encoding scheme uses. As it is now, the R900 decoder piggy-backs on the decoder used for the rest of the protocols since it's preamble is manchester coded while the rest of it's payload uses 4-chip symbols.

I've decided against writing a multiplexed rtl_tcp. I've refactored some of the DSP functions and buffers such that it will be easier to use a single decoder with multiple (similar) protocols since the only real difference between protocols is the length of new sample blocks and how many samples to keep in the quantized buffer.

I'm closing this issue in favor of continuing the conversation on the existing ticket: #39
