Recently, dynamic spectrum access (DSA) technique has been attracting attention for solving exhausting problem of the frequency spectrum. The DSA is a technique which exploits spatial and temporal spectrum white space.
In the wireless communication systems, the fading compensator is required in order to obtain the correct data from the distorted signal by multipath propagation. Since a DSA-based wireless communication system selects a set of spectrum referring to the result of spectrum sensing, the dedicated fading compensator considering the characteristics of DSA is required.
In this report, the fading compensator architecture for DSA is proposed. Piecewise linear interpolation is adopted to increase the channel estimation accuracy. The proposed architecture guarantees real-time processing with 76MHz or higher clock frequency.
The FPGA implementation of the proposed architecture occupies 1,577 slices and works up to 121MHz. |
