We consider compressed sampling over finite fields and investigate the number of compressed measurements needed for successful L0 recovery. Our results are obtained while the sparseness of the sensing matrices as well as the size of the finite fields are varied. One of interesting conclusions includes that unless the signal is “ultra” sparse, the sensing(More)
In wireless networks, advanced communication techniques exploited network coding and cooperative schemes have attracted considerable attention as ways to enhance power efficiency as well as to achieve high throughput and spectral efficiency. In this paper, we consider a cooperative wireless network with two nodes and one base station, and investigate the(More)
In this paper, we consider a cooperative wireless network in which there are multiple sources and multiple relays. Owing to unreliable wireless channels, the network connections between nodes vary. This leads to the failure of intermediate nodes for generating linear combinations of incoming messages in network coding schemes. We propose an analytical(More)
The use of low-density parity-check (LDPC) codes over the multi-input multi-output (MIMO) channels has shown the performance to be achieved to the capacity limit. For the 2 × 2 MIMO system, the Golden codes were recently developed as the optimal space-time codes with a full rate and a full diversity gain. In this paper, we give the detailed system(More)
