An optimal wideband spectrum sensing framework which identifies secondary transmission
opportunities over multiple nonoverlapping narrowband channels is presented. The …

This paper describes the results from a series of long-term observations of spectrum
occupancy in the range 300 MHz-4.9 GHz made at a single location. Over 6 months of data …

This letter analyzes the sensing-throughput tradeoff for a secondary user (SU) under random
arrivals and departures of multiple primary users (PUs). We first study the case where PUs …

Periodic spectrum sensing over the entire primary user (PU) band always interrupts the
secondary user (SU) data transmission in the sensing interval, which may degrade the …

In this paper we present a thorough study of spectrum sensing performance in cognitive
radio (CR) scenarios where the primary user (PU) transmission is not continuous. In …

In practical scenarios with random arrival and departure of primary users (PUs), existing
simultaneous sensing and transmission schemes allocated the same weight to each …

In this letter, the impact of primary user traffic with multiple status changes on the spectrum
sensing performance is analyzed. Closed-form expressions for the probabilities of false …

Summary 5G Internet of Things (IoT) networks are characterized by wideband radio
frequency spectrum utility and are therefore of primary importance for efficient means of …

With the miniaturisation of the computing devices, the technological market has seen a rapid
surge in various wireless technologies penetrating into our lives. The scarcity of spectrum is …

The effect of multiple primary users on spectrum-sensing performance is investigated.
Different models for primary user traffic are considered. The effects of different system …
