Yes, for LFSRs it is often the high ratio of auto/cross correlation for the particular encode phase, along with the ease of generation and deconvolution for sin

Yes, for LFSRs it is often the high ratio of auto/cross correlation for the particular encode phase, along with the ease of generation and deconvolution for single bit signaling at low SNR. I don't know that most other pseudo-random codes have this property.
