In data-dependent superimposed training (DDST) schemes, the data-induced interference that occurs during channel estimation is eliminated at the expense of data distortion. Unfortunately, this distortion causes a data identification problem (DIP), where data sequence cannot be uniquely determined at the receiver end. Although DIP has been widely investigated in the literature, an effective solution...
This work presents a novel peak-to-average power ratio (PAPR) reduction scheme, namely extended selected mapping (eSLM), in space-frequency block coding (SFBC) MIMO-OFDM systems. By introducing phase rotations and amplitude extensions into so-called extension matrices, the candidate signals with lowest PAPR can be selected and the receiver is able to identify index of the selected candidate without...
Orthogonal frequency division multiplexing (OFDM) and interleave-division multiple-access (IDMA) are both attractive technique in modern wireless communication. In this paper, we study a multi-user system, which combines OFDM and IDMA, and fortunately, inherits many advantages. In order to improve system performance, low-density parity-check (LDPC) coding is further applied. And moreover, a turbo-type...
This paper considers the joint symbol detection and channel estimation problem for cooperative communications in cluster-based networks. The proposed joint detection and estimation scheme is derived by using the expectation maximization (EM) algorithm. In addition, the cooperative communication between the relays and the destination is based on the concept of compress-and-forward (CF) scheme. Most...
