Xilinx Virtex II Pro implementation of a reconfigurable UMTS digital channel filter

In English A reconfigurable digital root raised cosine (RRC) filter for a UMTS terrestrial radio access (UTRA) mobile terminal receiver is implemented on a Xilinx Vitrex II Pro Field Programmable Gate Array (FPGA). The filter employs a finite impulse response (FIR) and monitors in-band and out-of-band received signal powers and calculates the appropriate filter length that meets the bit-energy to interference ratio (Eb/No) of the system. The results presented are for the time division duplex (TDD) mode of UTRA.
