Abstract: A technology is described for moderating output confidence of output soft information associated with a MIMO detector. An example method can include generating output soft-information that is a measure of likelihood that a subset of bit sequence permutations correctly represents a bit sequence extracted from a radio signal received by the MIMO detector. Calculating a distance of the subset of bit sequence permutations to the bit sequence extracted from the radio signal. Determining that the output confidence of the output soft-information warrants adjustment of the output confidence of the output soft-information based in part on the distance of the bit sequence extracted from the radio signal to the subset of bit sequence permutations. And adjusting the output confidence of the output soft-information based in part on the distance of the bit sequence extracted from the radio signal to the subset of bit sequence permutations using an adjustment technique.

Abstract: A technology is disclosed and described for processing a radio signal using an excited Markov Chain Monte Carlo (MCMC) Gibbs sampler. An example method (200) may include calculating a distance (210) of a bit sequence from an estimated correct bit sequence, where the bit sequence may be extracted from a received radio signal received by a Multiple-Input and Multiple-Output (MIMO) detector. An excitation factor may be modified (220) based in part on the distance of the bit sequence from the estimated correct bit sequence, where the where the excitation factor may be used in part to calculate a probability of state transition of the bit sequence. A pseudo-convergence of the probability of state transition of the bit sequence may be detected (230) and a pseudo-convergence mitigation technique may be executed (240) that causes the probability of state transition of the bit sequence to increase.

Abstract: A system including an external medical data telemetry device to communicate with an implantable medical device (IMD). The external medical data telemetry device includes a processor, a reconfigurable radio-frequency (RF) transceiver circuit, at least one far-field antenna, and a user interface. The reconfigurable RF transceiver circuit modulates an outgoing IMD data signal and demodulates an incoming IMD data signal using a modulation type that is selectable from a plurality of modulation types by the processor. The processor selects the modulation type using information entered by a user through the user interface.
