Digitally programmable multifunction radio system architecture

A digitally programmable multifunctional radio comprising:

• an antenna for receiving an RF signal;
• an antenna interface module, coupled to said antenna, for performing preprocessing of the RF signal;
• and
• a common receive module, coupled to said antenna interface module and internally programmably reconfigurable and self-contained for channelized operation in each of a plurality of different radio modes, for frequency translating the preprocessed RF signal into an analog signal, converting the analog signal into a digital signal and digitally processing the digital signal into a bit stream,
• said common receive module and said antenna interface module being optimally partitioned such that said common receive module includes components that are programmably reconfigurable for operation in all of the plurality of different radio modes and said antenna interface module includes only components that are dedicated for operation only in a single or relatively few of the plurality of different radio modes.

A digitally programmable multifunctional radio comprising:

• a common transmit module, internally programmably reconfigurable and self-contained for channelized operation in each of a plurality of different radio modes, for digitally processing a first bit stream into a first digital signal, converting the first digital signal into a first analog signal and frequency translating the first analog signal into a first RF signal;
• an antenna for receiving a second RF signal;
• an antenna interface module, coupled to said antenna and said common transmit module, for performing further processing of the first RF signal, providing the further processed first RF signal to said antenna for transmission and performing preprocessing of the second RF signal;
• and
• a common receive module, coupled to said antenna interface module and internally programmably reconfigurable and self-contained for channelized operation in each of the plurality of different radio modes, for frequency translating the preprocessed second RF signal into a second analog signal, converting the second analog signal into a second digital signal and digitally processing the second digital signal into a second bit stream,
• said common transmit module, said common receive module and said antenna interface module being optimally partitioned such that said common transmit module and said common receive module include components that are programmably reconfigurable for operation in all of the plurality of different radio modes and said antenna interface module includes only components that are dedicated for operation only in a single or relatively few of the plurality of different radio modes.
