This paper investigates setup optimization of Spatial Modulation (SM) systems. Specifically, the optimal pair of the number of the transmit antennas and the modulation order, for a given spectral efficiency, that minimizes the error rate at the receiver has been discussed. Interesting results regarding the behavior of bit error rate and symbol error rate(More)
The authors discuss the importance of using the singular value decomposition (SVD) in computing the capacity of multiple input multiple output (MIMO) and in estimation the channel gain from the transmitter to the receiver. Examples that show how the SVD simplifies computing the MIMO channel capacity are discussed. Numerical results that show what factors(More)
This paper proposes a novel data gathering scheme for Wireless Sensor Networks (WSN) that limits the energy expenditure, and hence, prolongs network lifetime. Data gathering is modeled as an auction where a node broadcasts its own result only if it is higher than the maximum already-broadcasted result by other nodes. For a WSN of 100 nodes, mathematical and(More)
During the last few years, the revolution of social networks such as Facebook, Twitter, and Instagram led to a daily increasing of data that are heterogeneous in their sources, data models, and platforms. Heterogeneous data sources have many forms such as the www, deep web, relational databases systems, No-SQL database systems, hierarchal data systems,(More)
