A method and system for performing quadrature amplitude modulation (QAM) decoding of a received signal includes finding for each layer a region in a first constellation diagram of the received signal, the region including a portion of the first constellation diagram, the portion having the same size of a second constellation diagram, and a first constellation order of the received signal is higher than a second constellation order of the second constellation diagram; and, for each layer: finding a first portion of bits based on bits that are constant among constellation points located in the region of the layer; decoding the received signal using a QAM decoder having the second constellation order to obtain a second portion of bits; adjusting the second portion of bits based on the region of the layer; and merging the first portion of bits with the second portion of bits to obtain a decoded symbol.

System and method for using low complexity maximum likelihood decoder in a mimo decoder

A method and system for performing Maximum Likelihood Detector (MLD) preprocessing in a Multiple-Input Multiple-Output (MIMO) communication system, the method including, obtaining a received signal Y a corresponding channel matrix H and a vector of noise samples n; calculating a whitening filter L; whitening a channel matrix H; selecting one of a first calculation or a second calculation, based on estimated complexity of the calculations; and performing preprocessing of the received signal using the selected calculation. The first calculation includes: whitening the received signal and performing a Cordic based QR decomposition to the whitened channel matrix {tilde over (H)} and the whitened received signal {tilde over (Y)} to obtain triangular matrix R and=QLY. The second calculation includes: performing a Cordic based QR decomposition to the whitened channel matrix {tilde over (H)} and the whitening filter Lto obtain triangular matrix R and QL, and multiplying the received signal Y by QLto obtain=QLY.

System and method for performing MLD preprocessing in a MIMO decoder

Systems and methods are described, including a system for electrostimulation. The system includes a patch (), including a plurality of electrodes (), and a mobile device (). A processor () of the mobile device is configured to receive an input from a subject () that indicates that the subject is experiencing a headache, and, in response to the input, while the patch is coupled to the subject, wirelessly communicate a control signal that causes the electrodes to stimulate the subject. Other embodiments are also described.
