Abstract :
Paper presents the implementation of digital baseband signal processing with Output Shifted Coded Modulation (OSCM) function on Digital Signal Processor (DSP) Kit TMS320C6711. Single DSP chip is used to implement the baseband processing function due to compactness, low-power consumption and flexibility. Although FPGA is compact and high performance, it consumes much more power whereas ASIC has the downside of limited flexibility. C6711 is a member of the high performance DSP family from Texas Instruments (TI) that incorporated the realtime kernel known as DSP/BIOS. The design environment is based on Code Composer Studio IDE (Integrated Development Environment) and the DSP functions are simulated on 150 MHz clock C6700 DSP simulator. The research begins with designing the DBSP functions and then optimized the source codes using lookup table method and DSP/BIOS modules. Finally, the optimized codes are implemented on TMS320C6711 DSK and the codes performances are collected through DSP/BIOS analysis modules.
