Abstract
In this letter, we investigate the concatenation of a low density generator matrix (LDGM) outer code and a recursive space time trellis (RSTTC) inner code based on differential encoding. We provide guidelines for the design of the LDGM outer code and observe that previous schemes based on parity check outer codes are particular cases of the proposed framework.
