This paper investigates performance of the constrained partial group decoding (CPGD) technique in interference channel (IC) environment. It demonstrates the CPGD capability to manage and mitigate interference comparing with other interference mitigation schemes which are based on interference alignment strategy; this comparison is carried out for MIMO(More)
In this paper we aim to assess the performance of the optimal successive group decoder (OSGD) in the wireless interference channel (IC) for different scenarios using wide range of testing metrics. Therefore, we inspect the capability of OSGD to mitigate interference, also, we evaluate its minimum required energy per bit under specific quality of service(More)
—In this study we aim to assess the optimal successive group decoder (OSGD) considering different scenarios and in a wide range of testing metrics. We investigate the OSGD in the K−user interference channel (IC) and evaluate its capability to mitigate interference. We inspect OSGD performance in terms of its (ergodic and effective) capacity. Also, we(More)
In modern greenhouses, several measurement points are required to trace down the local climate parameters in different parts of the big greenhouse to make the greenhouse automation system work properly. Cabling would make the measurement system expensive and vulnerable. Moreover, the cabled measurement points are difficult to relocate once they are(More)
We proposed a very simple method of eliminating faulty distance estimates by filtering the measured RSSI through optimized SD and packet loss limits. We conducted experiments with CC2431 radio nodes to collect enough RSSI measurements for model parameter estimation. We devised an optimizer to find optimized model parameters and limits. Then we used the(More)
— This paper investigates optical power control to enhance capacity of optical CDMA star coupled networks. We consider a network in which the nodes encode their optical signal by prime codes, and the resulting error rate performance is inspected with and without power control. Network impairments, such as fiber attenuation, star coupler loss, thermal noise(More)
