The performance of a full-duplex (FD) relaying system is investigated in this paper. The relay is equipped with two antennas (both are trans-receiver). The energy constrained relay is powered by RF energy harvesting. A time-switching architecture is adopted to make communication between a source and a destination. Information received at the destination from both the trans-receiver is combined using a soft combining technique, i.e., Maximal Ratio Combining (MRC). The performance of two protocols, decode-and- forward (DF) relaying and amplify-and-forward (AF), are also studied and compared. It is found that use of double antenna instead of single antenna based transmission at the relay improves the performance significantly. The impact of MRC on the throughput performance is noticeable. © 2018 IEEE.

Performance of Full Duplex Relaying with Dual Antenna and Soft Combining

2018 2nd International Conference on Trends in Electronics and Informatics (ICOEI)

In this paper, the impact of a multi slot based cooperative spectrum sensing (CSS) on the performance of a cognitive radio (CR) network has been investigated. Each CR user, equipped with an improved energy detector (IED), uses a number of mini slots of the sensing time to perform the spectrum sensing. Each CR uses OR logic to combine the sub local decisions generated in each mini slot to obtain a local decision at CR level. Local decisions are sent to fusion centre (FC) over reporting channel. The FC obtains a final decision about the presence of primary user (PU) by combining the local decisions using a fusion rule: Majority or Maximal Ratio Combining. The performance of the CSS is assessed in terms of detection probability and false alarm probability considering both the sensing and reporting channels are Rayleigh faded. Furthermore, the impact of a number of sensing slots and IED parameter on throughput of CR network is also evaluated under the proposed spectrum sensing scenario. Impacts of several sensing parameters such as sensing channel SNR and reporting channel SNR on the performance of CR network are also evaluated. Performances of two fusion rules under study are compared. Effect of sensing error and synchronisation error is indicated. Further the study is extended for independent but non identically distributed (i.n.i.d.) Rayleigh faded channels as well as for a multiple PU scenario also. © 2017, Springer Science+Business Media New York.
