Combined Frequency and Time Domain Channel Estimation in Mobile MIMO-OFDM Systems

Overview This paper proposes a combined frequency and time domain channel estimation method for MIMO OFDM systems. Initial channel estimation is performed by first estimating the channel response in frequency domain, exploiting a set of dedicated pilot carriers, followed by an interpolation step. In order to reduce the interpolation error and improve the bit error rate performance, the paper proposes to refine the channel estimates in time domain using the equalized signal from the frequency domain processing.

Radioactive: Bluetooth - survival of the fastest

The former method, backed by Intel, is more complex: it chops up the signal and sends it over multiple frequency bands. The opposing technology approaches are orthogonal frequency division multiplexing (OFDM) and direct sequence (DS)-UWB.

Virtualisation: Architectual Considerations and other Evaluation Criteria

In the past several years, server virtualisation technology has moved quickly and firmly into the IT mainstream. Of the many approaches to system virtualisation available in the market today, VMware's hypervisor architecture has gained the greatest market acceptance. This paper examines the architectural issues, solution support, and enterprise readiness required when deploying such a virtualisation solution.
