We propose a new class of transceivers for secure communication and interference mitigation, operating over large bandwidths on the order of 10GHz. Specifically, a novel coding approach that combines frequency and code multiplexing is proposed. Equally important is power and hardware reduction by implementing a low power on-site coding with beamforming. The latter reduces power requirements for the digitizer by a factor of 8 to 32. In this paper, we present a description of the proposed high data system and integrated coding scheme. System performance is also evaluated in presence of interference and noise analysis is conducted to assess the impact of coding for different noise floors. Preliminary results show minimal degradation using orthogonal Walsh-Hadamard codes using ideal filters and a minimum digitizer resolution of 5 bits.
