1. A magnetic resonance imaging (MRI) lucent, wirelessly-chargeable, implantable medical device, comprising:
an MRI-lucent housing; and
an MRI-lucent antenna contained in the housing and configured to wirelessly receive an electromagnetic signal from a signal source external to the housing, wherein the signal source further comprises:
a primary modulator configured to combine a raw signal with a carrier signal to provide a signal having continuous phase modulation; and
a secondary modulator configured to combine the signal having continuous phase modulation with a pseudorandom noise sequence to provide a signal having direct sequence spread spectrum modulation, wherein the signal having direct sequence spread spectrum modulation is input to an antenna of the signal source.
