Abstract :
We propose an experimental validation of a novel hardware-reduced digital beamformer. The novelty of this receiver is a coding technique so that a single analog-to-digital converter serves all antenna array elements. We present a two-channel component implementation (with COTS components) of this receiver using Walsh-Hadamard codes of length 8. The main purpose of this implementation is to establish a proof of concept and show that we can recover the input signal and beam direction. Measurements results show signal recovery with minimal SNR degradation.
