a transceiver having substantially improved capacity and interference mitigation . the transceiver comprises a first direct conversion receiver and a plurality of additional dcrs , each of the plurality of additional dcrs having essentially identical constituent components to the first dcr . each dcr does a direct down - conversion from rf to a complex pair of baseband i and q components . the complex signal pair from each dcr is digitized and further processed in a modem module where the signal is optimally filtered , demodulated , and error - corrected . the modem module reconstructs the message information contained in each signal from all of the dcr &# 39 ; s , simultaneously providing the demodulated data that was contained in the rf signals . the dynamic range of the system is extremely large .
