On the implementation of a baseband processor for a portable dual mode DECT/GSM terminal

For the implementation of a multi-mode DECT/GSM wireless terminal, a dual mode baseband processor, namely ASPIS processor, capable to undertake all baseband signal processing required is designed and fabricated. The multi-mode wireless terminal is based on direct conversion architecture. Experimental results from the operation of ASPIS processor and performance analysis of the selected architecture, under two different testing environments, are promising and quite satisfactory.
