Hi,
i am implementing ofdm modem using dsp5140. My old circuit board is having tlv320ad50 codec. I am not geeting proper signal shapes at the output of DAC after sample rate is increased to 64 K. Other wise at 16K sample rate Tx and Rx are behaving properly at baseband.
can anybody help with...

in ccs u can make your projects, built in and load into the target board. CCs supports .c , .asm , .h etc files. also different files can be taken together in a project. CCS also offer you very good out viewing of the results be it in graph form of raw data.
decimation is nothing but decreasing the samples/sec and accordingly shifting the freq spectrum towards DC.
interpolation is adding more sampling points in between the the samples of interest. Filtering is required to curb the outgoing spectral components.
this is very brief answer ,i thing.
