Cooperative Diversity Based on LDPC Code
Diversity is an effective method to resist the fading effect in wireless channel. Limited by size, weight and cost, it is difficulty to use the multi-antenna technique on the terminal of wireless communication. Cooperative communication allows the sharing of the antennas among the mobile terminals which have single antenna. Thus creates virtual multi-antenna, and realizes transmitting diversity. LDPC code is a good linear block code. By using the intrinsic coherence among the bits of the code word, we can create a coded cooperative communication among the mobile users to effectively improve the system performance. This paper proposes a cooperative communication method based on LDPC code, and provides the simulation results.
