This paper proposes low complexity resource allocation in frequency domain non-orthogonal multiple access where many devices with a base station. The number of the is assumed to be more than that for network capacity enhancement, which demanded massive machine type communications (mMTC). two types techniques, all are based on MIN-MAX approach. One them seeks nicer only channel gains. other tech...

This paper studies a federated learning (FL) system, where multiple FL services co-exist in wireless network and share common resources. It fills the void of resource allocation for multiple simultaneous existing literature. Our method designs two-level framework comprising intra-service inter-service allocation. The intra-service problem aims to minimize length rounds by o...

Several recent studies suggest that co-allocation techniques can improve user performance for distributed data retrieval in replicated grid systems. These studies demonstrate that co-allocation techniques can improve network bandwidth and network transfer times by concurrently utilizing as many data grid replicas as possible. However, these prior studies evaluate their techniques from a single ...

We study the joint optimization problem of a transmitter with multiple transmit antennas and a receiver with multiple receive antennas in a narrow-band communication system. We discuss the problem of designing a pre-filter at the transmitter, a post-filter at the receiver, and a bit allocation pattern to multiple symbols in the sense of minimizing the average bit error rate. With the optimized ...

The problem of power allocation is studied for a multiple-input multiple-output (MIMO) decode-and-forward (DF) two-way relaying system consisting of two source nodes and one relay. It is shown that achieving maximum sum-rate in such a system does not necessarily demand the consumption of all available power at the relay. Instead, the maximum sum-rate can be achieved through efficient power allo...
