Abstract
This disclosure describes to techniques to compensate for distortions introduced into received signals by one or more receiver components that have undesirable electrical responses, such as nonlinear phase response, sloped (or non-flat) amplitude response or both. An external device or other device with more power resources than an IMD filters signals to be transmitted to the IMD to pre-compensate for distortions introduced by the undesired electrical responses of the one or more receiver components of the IMD. In this manner, at least a portion of the burden of digital processing to compensate for undesired electrical responses of the receiver components is shifted from the IMD to the external device, which is better equipped to perform such heavy computationally complex functions.
