  • Demapper for rotated QAM constellations
    Patent number: 9143377
    Abstract: Techniques are described for quadrature amplitude modulation (QAM) processing in a rotated QAM constellation. In the techniques, one or more processors determine points within the rotated QAM constellation around a vector location of a received symbol based on a probability density function applied to the vector location. The one or more processors map the points to corresponding mapped symbols of the rotated QAM constellation, and determine a plurality of bits represented by the transmitted symbol based on the corresponding mapped symbols.

  • Methods and apparatus for signal conditioning for polar transmitters
    Patent number: 8855231
    Abstract: Methods, systems, devices, and apparatuses for signal condition of polar transmitters are discussed this patent application. According to one embodiment, a frequency limiting mechanism for a polar transmitter can perform minimal distortion frequency limiting to comply with the polar transmitter requirements while meeting emissions specifications. Embodiments of the present invention may be utilized as features or components of wireless communication devices to enable minimal distortion to information carrying signals and to meet emissions specifications. Other aspects, embodiments, and features are claimed and discussed above.
