TABLE OF CONTENTS As the number of wireless communication systems that users can use increase, there has been increasing demands for the coexistence of several mobile telecommunication services; for example, GSM, or IS-54, or IS-136, or IS-95, Japanese Personal Digital Cellular (PDC) or Personal Handy Phone System (PHS) or IMT-2000 system. Currently, if one wants to be globally connected, more than one terminal may be needed, though it is becoming more common to find multistandard terminals.
A person working on SDR is expected to be familiar with any communication system whether it is for radio transmission or multiple access purposes. Such schemes can be developed and written in programming languages like MATLAB or C. These computer simulation languages have a good relationship with software languages that configure digital signal processing hardware (DSPH) such as digital signal processors (DSP), field programmable gate arrays (FPGA), and application-specific integrated circuits (ASIC). A typical software language for DSPH is very high speed integrated circuit hardware description language (VHDL) and Verilog-HDL. DSPH has been utilized to configure the mobile terminals and base stations of mobile communication systems. DSPH is a general-purpose language, and the configuration can be programmed by downloading digital signal processing software (DSPS). This means that users can download DSPS describing the desired elemental components into the DSPH of only one terminal. This is the basic concept of an SDR communication system [76 90].
Software defined radio in theory will allow mobile terminal manufacturers to design and manufacture products that...
