Error Estimation Scheme Using AMI Code for Detect-and-Forward Multi-hop Communications

Kotoko Yamada and Kouji Ohuchi
Abstract—DetF (Detect-and-Forward) is one of the relaying schemes for multi-hop communications. In DetF, each relay node determines the data bit in the packet by hard-decision and only the destination node decodes and corrects the packet. If each relay node can observe how many errors are accumulated in the packet it relays, it can notice a good opportunity for decoding and correcting the accumulated errors in the packet. For DetF with error detection, we need the error detection scheme which can detect not only the existence of errors but the amount of errors. This paper focuses on a modified TPSK (ternary phase shift keying) using AMI (alternate mark inversion) code which can estimate the amount of errors easily. We compare this error detection scheme with BPSK (binary phase shift keying) using parity check code. This paper evaluates error estimation performance of these error detection schemes in multi-hop communications under fading environments. As a result, the modified TPSK with phases 0, 135 and -135 deg is the most proper to an error detection scheme for DetF.

Index Terms—Multi-hop network, parity check code, AMI code, error estimation.
