In this paper, we investigate the relaying issue of Zero-Padding (ZP) Orthogonal Frequency Division Multiplexing (OFDM) technique to estimate Time Difference of Arrival (TDOA) for locationing applications. In order to benefit from the easy processing of Amplify-and-Forward (AF) relay as well as the noise and interference cancellation of Decode-and-Forward (DF) relay schemes, we introduce the trigger...
In this paper, we design a cooperative wavelet scheme for the multi-relay, multi-scale and multi-lag diversity, which can be widely applied in the ultra-wideband communications and underwater acoustic communications. A Decode-and-Forward (DF) cooperative relay network is set for the multi-scale and multi-lag wideband channels. Then, an analytical bit error rate (BER) expression for this DF cooperative...
In the cooperative communication system, due to the distributed nature of the relay system, multiple carrier frequency offsets (CFOs) at different relays and multipath channels between relays cause the whole cooperative communication channel to be a doubly time-frequency selective channel. Zero-Padding Orthogonal Frequency Division Multiplexing (ZP-OFDM), which has been adopted for some wideband communication...
Cooperative communication technique relies on the relay selection and power allocation process to optimize its performance. Optimal relay selection using game theory can lead to maximum benefit for both the source and the relay nodes. In this paper, we propose a Stackelberg game model for cooperative wireless communication networks with interference. The simulation result shows that interference coming...
The emerging technology of cooperative communication has been intensively examined in the recent years. However, few investigate its combination with the Multi-band (MB) OFDM physical layer. In the paper, we propose a cooperative MB-ODFM communication with efficiently grouped relays under multipath channel. Taking advantage of the multiple bands together with the grouped relays, the proposed zero-padding...
Cooperative diversity networks have been receiving a lot of attention recently as an attractive way to combat frequency-selectivity of wireless channel, as it consumes neither time nor frequency resources. In the conventional cooperative strategies, relays employ either a decode-and-forward (DF) or an amplify-and-forward (AF) relaying protocol. In this paper, we investigate a new hybrid cooperative...
