Abstract EN
The Fourth Generation (4G) network is expected to serve mobile subscribers under dynamic network conditions and offer any type service: anytime, anywhere, and anyhow.
Two such technologies that can respond to the above said services are Wideband Code Division Multiple Access (WCDMA) and Orthogonal Frequency Division Multiplexing (OFDM).
The main contribution of this paper is to propose a dedicated hardware module which can reconfigure itself either to the OFDM Wireless LAN or WCDMA standard.
In this paper, Fast Fourier Transform (FFT) algorithm is implemented for OFDM standard, and rake receiver is implemented for WCDMA standard.
Initially efficient implementations of these two algorithms are tested separately and identified the resources utilized by them.
Then the new hardware architecture, which configures to any one of these two standards on demand, is proposed.
This architecture efficiently shares the resources needed for these two standards.
The proposed architecture is simulated using ModelSimSE v6.5 and mapped onto a virtex 5 FPGA device (xc5v1x30ff324) using the tool Xilinx ISE 9.2i, and the results are compared with the standard approach.
These results show that the proposed hardware architecture utilizes less number of resources compared to the conventional Reconfigurable Receiver Architecture System.
