- QoS Challenges and Opportunities in Wireless Sensor/Actuator Networks
- A Wireless Sensor/Actuator Network WSAN is a group of sensors and actuators that are geographically distributed and interconnected by wireless networks. Sensors gather information about the state of physical world. Actuators react to this information by performing appropriate actions. WSANs thus enable cyber systems to monitor and manipulate the behavior...

- On Cyclic Delay Diversity in OFDM Based Transmission Schemes
- Cyclic Delay Diversity CDD is a simple approach to introduce spatial diversity to an Orthogonal Frequency Division Multiplexing OFDM based transmission scheme that itself has no built-in diversity. It also can be regarded as a Space-Time Code STC. But in contrast to that there is no additional effort in the...

- Differential Modulation Diversity for OFDM
- The application of Differential Modulation Diversity DMD to orthogonal frequency division multiplexing with multiple transmit and/or receive antennas is considered. Based on diagonal signals originally designed for differential space-time modulation, DMD is used to exploit both space and frequency diversity. At the receiver, low-complexity decision-feedback differential detection without channel state...

- Maximum Achievable Diversity for MIMO-OFDM Systems With Arbitrary Spatial Correlation
- In this paper, the maximum achievable diversity order is determined for MIMO-OFDM systems with arbitrary spatial correlation. This paper shows that the maximum achievable diversity order is the rank of the spatial correlation matrix of the channel including all delay paths. The paper also shows that any space-frequency code designed...

- Cooperative Diversity in Wireless Networks: A Geometry-Inclusive Analysis
- Cooperation between physically separated wireless nodes can achieve the high Signal-to-Noise Ratio SNR diversity gains characteristic of multi-antenna arrays. Simulations indicate that such gains are still achieved for SNRs in the range of practical interest for several applications. Cooperation further yields SNR gains in addition to diversity gains. In contrast...
