In this paper, two compact quad-channel and six-channel diplexer are designed and fabricated using defected microstrip structure (DMS). This structure is designed for the desired frequency based on the literature reviews. The proposed configuration is composed of a conventional T-junction divider with two pairs of open bended stubs and dual/tri-band filters. In designing dual band filters, a lo...

The number of mobile devices, IoT and their applications is increasing day by in recent years further going to increase coming years. These devices demand large connectivity, high throughput, low latency which can be possible only the B5G or 6G. effective utilization spectrum done multiple access techniques facilitate accommodate a users. 5G has different new technologies support massive user h...

In a multi-group multicast sparse code multiple access (SCMA) system, one base station multicasts common messages to groups via different books. To accommodate more user terminals (UTs), traditional systems have transmitters, each of which works in one-to-many mode. this way, UT is subject inter-transmitter interference. Considering the high degrees freedom for transmitting and receiving, it di...

Stream control has recently attracted attentions in the research of MIMO wireless networks as a potential way to improve network capacity. However, inappropriate use of stream control may significantly degrade network capacity as well. In this paper, we provide the first formal study on stream control scheduling in MIMO wireless mesh networks. We derive the theoretical upper bound on network ca...

This paper studies intertemporal investment strategies under inflation risk by extending Merton’s intertemporal framework (1973) to include a stochastic price index. The stochastic price index gives rise to both real and nominal terms of valuation: agents maximize their utility of consumption in real terms while investment activities and wealth evolution are evaluated in nominal terms. We inclu...
