| description |
In this thesis, the Software Defined Radio Digital Control System (SDR DCS) has
been developed to perform a multi-standard protocol of the handset using the GSM
and CDMA systems. The SDR DCS was designed for the SDR based band digital
transceiver of the handset as a control and protocol software to control and handle
the operation of the handset when roaming between different protocols; it could
easily and quickly let the handset reconfigure with the future protocol; it configured
the handset with either of the GSM or CDMA protocol software, and scheduled for
reconfiguration of the handset with the second protocol in sequence. The SDR DCS
controls the download of the specific air interface environment.
In order to implement the whole design in software, the design had to go through
three stages. The first stage was to do all the design steps in the software using
generic computing resources such as Hardware Description Language (HDL), with
the top-level design for each protocol. The second stage was to define a logic circuit
to perform the signal processing for each protocol; this step was applied after the
simulation and synthesis, and eventually programming that circuit into the FPGA board. The third stage was to use the FPGA to implement the functions required for
each protocol which constitutes the multi-standard protocol.
The VHDL files were created for each element of the GSM and CDMA protocols.
The GSM related system was developed with encoders and decoders linked to the
channel model. The CDMA related system was designed with a transmitter to
encode the user’s data into wide bandwidth using a reverse link channel and a
synchronized receiver to receive the signal from the forward link channel and decode
the wide bandwidth to recover the base band user’s data.
The Synopsys™ software package was used for the design, synthesis and simulation
of the SDR base band platform. The simulation tools used include the Model Sim
and System Studio. Meanwhile, the Xilinx ISE 9.2i was used as the synthesis tool.
The results of the simulated and synthesized top-level design files were downloaded
into the Xilinx XSA-3S1000 FPGA board. The waveforms for the GSM and CDMA
outputs approximately matched the ones seen in the oscilloscope for the FPGA
output pin. This proved that the SDR DCS had successfully implemented its task,
according to the objectives of the design. |
