Blind Channel Estimation for Amplify-and-Forward Two-Way Relay Networks Employing M-PSK Modulation
We consider the problem of channel estimation for amplify-and-forward (AF) two-way relay networks (TWRNs). Most works on this problem focus on pilot-based approaches which impose a significant training overhead that reduces the spectral efficiency of the system. To avoid such losses, this work proposes blind channel estimation algorithms for AF TWRNs that employ constant-modulus (CM) signaling....
متن کاملExact Cramer-Rao Bounds for Semi-blind Channel Estimation in Amplify-and-Forward Two-Way Relay Networks
In this paper, we derive the exact Cramer-Rao bounds (CRBs) for semi-blind channel estimation in amplifyand-forward two-way relay networks employing square QAM modulation. The derived bounds are used to show that the semiblind approach, which exploits both the transmitted pilots and transmitted data symbols, can provide substantial improvements in estimation accuracy over the training-based app...
متن کاملSemi-blind Channel Estimation for Amplify-and-forward Cooperative Relay Networks
We consider channel estimation in amplify-andforward wireless relay networks when coherent distributed spacetime coding is performed at the relays. Employing minimum mean-square-error signal detection at the destination, we first bring clearance on the detector formulation when only partial channel state information is available. We then consider channel estimation and propose to use a semi-bli...
متن کاملIndirect Channel Sensing for Cognitive Amplify-and-Forward Relay Networks
—In cognitive radio network the primary channel information is beneficial. But it can not be obtained by direct channel estimation in cognitive system as pervious methods. And only one possible way is the primary receiver broadcasts the primary channel information to the cognitive users, but it would require the modification of the primary receiver and additional precious spectrum resource. Coo...
متن کاملChannel Estimation for Two-Way Relay OFDM Networks
We consider the channel estimation for two-way relay OFDM networks. We proposed an LS-based channel estimation algorithm under block-based training schemes. Based on the mean square error (MSE) criterion, the condition and the design method for optimal training sequences are discussed. To reduce peak-to-average power ratio (PAPR), a special sequence called Zadoff-Chu sequence is employed to des...
