  • Patent number: 12021668
    Abstract: Described apparatuses and methods are directed to equalization with pulse-amplitude modulation (PAM) signaling. As bus frequencies have increased, the time for correctly transitioning between voltage levels has decreased, which can lead to errors. Symbol decoding reliability can be improved with equalization, like with decision-feedback equalization (DFE). DFE, however, can be expensive for chip area and power usage. Therefore, instead of applying DFE to all voltage level determination paths in a receiver, DFE can be applied to a subset of such determination paths. With PAM4 signaling, for example, a DFE circuit can be coupled between an output and an input of a middle slicer. In some cases, symbol detection reliability can be maintained even with fewer DFE circuits by compressing a middle eye of the PAM4 signal. The other two eyes thus have additional headroom for expansion. Encoding schemes, impedance terminations, or reference voltage levels can be tailored accordingly.

    Abstract: Techniques for optimizing connection stability via communications with base stations in wireless communication networks. A current actual signal-to-distortion measurement value is determined for signals received by a device from a base station in a wireless communication network. A target base station configuration is determined based on the actual signal-to-distortion measurement value and known relationships between signal-to-distortion measurements and reliability metrics corresponding to different base station configurations. Deceptive signal quality transmissions are sent to the base station until the base station selects the target base station configuration. The deceptive signal quality transmissions may include deceptive signal-to-distortion measurements or deceptive binary values indicating poor signal quality.
