Abstract :
A delay and sum beamformer (DSB) is used to process somatosensory evoked potentials (SEP) in the presence of myoelectric signal interference. An interference model is presented and signal-to-interference-plus-noise ratio (SINR) gains obtained by the delay and sum beamformer for in vivo neuromuscular signals are compared to theoretical results
