Abstract
This paper presents the architecture design,
FPGA implementation and test results of an
uplink baseband transceiver for W-CDMA
systems. The architecture is designed based
on 3GPP Radio Access Network FDD mode
specification. In addition, advance techniques
such as beamforming and RAKE receiving
are adopted. The beamformer uses spatial
signature calculated by the beam searcher to
combine input signals from four antennas
and therefore a spatial diversity gain is
introduced. A path diversity is provided by
the RAKE receiver, which gathers four
multi-path signals with the weights obtained
from the channel estimator for maximum
ratio combining. Scalar channel and vector
channel models are both used in the
simulation to verify the design. Both
simulation and hardware emulation results
show that the proposed architecture can
indeed meet the specified requirement, and
the advanced techniques, such as
beamformer, really provide an enhancement
in reception.
