Decoding of Variable Length PLH Codes

In this paper, we address the problem of decoding variable length physical layer header (PLH) codes. We take as a case study DVB-S2X standard, and, after selecting suitable PLH code with codeword length, propose two alternative noncoherent strategies. The proposed strategies allow to estimate transmitted field, which is unknown at receiver, jointly code. demonstrate that it possible achieve an excellent performance while significantly reducing overhead due transmission field respect standard fixed-length PLH.
