Additional analysis of SCCCs was done in "Coding Theorems for 'Turbo-Like' Codes" by D. Divsalar, Hui Jin, and Robert J. McEliece.<ref>{{cite web|url=http://www.mif.vu.lt/~skersys/vsd/turbo/Allerton98.pdf |title=Allerton98.tex |format=PDF |date= |accessdate=2014-06-04}}</ref> This paper analyzed repeat-accumulate (RA) codes which are the serial concatenation of an inner two-state recursive convolutional code (also called an 'accumulator' or parity-check code) with a simple repeat code as the outer code, with both codes linked by an interleaver. The performance of the RA codes is quite good considering the simplicity of the constituent codes themselves.
SCCC codes were further analyzed in "Serial Turbo Trellis Coded Modulation with Rate-1 Inner Code".<ref>[https://web.archive.org/web/20100529020555/http://trs-new.jpl.nasa.gov/dspace/bitstream/2014/18647/1/99-2030.pdf NASA.gov]</ref> In this paper SCCCs were designed for use with higher order modulation schemes. Excellent performing codes with inner and outer constituent convolutional codes of only two or four states were presented.
