  • Patent number: 10651903
    Abstract: Examples described herein include systems and methods which include wireless devices and systems with examples of an autocorrelation calculator. An electronic device including an autocorrelation calculator may be configured to calculate an autocorrelation matrix including an autocorrelation of symbols indicative of a first radio frequency (“RF”) signal and a second RF signal. The electronic device may calculate the autocorrelation matrix based on a stored autocorrelation matrix and the autocorrelation of symbols indicative of the first RF signal and symbols indicative of the second RF signal. The stored autocorrelation matrix may represent another received signal at a different time period than a time period of the first and second RF signals. Examples of the systems and methods may facilitate the processing of data for wireless and may utilize less memory space than a device than a scheme that stores and calculates autocorrelation from a large dataset computed from various time points.

  • Patent number: 10574311
    Abstract: A method of sounding and feedback with channel quality information and reduced overhead is provided. A receiving station receives a sounding signal transmitted from an access point over multiple sub-channels of a wide channel in a wireless network. The receiving station detects channel quality based on the received sounding signal for each sub-channel. The receiving station then performs channel estimation based on the received sounding signal and thereby determining feedback information. Finally, the receiving station transmits a feedback message to the access point, the feedback message contains NULL feedback information, reduced feedback information, or channel integrity/quality indicators based on the channel quality information for each sub-channel. Based on the feedback message, the access point may repeat the sounding process, narrow the transmission bandwidth, or select only stations who have indicated uncorrupted channel sounding for MU-MMO transmission.

    Abstract: There is provided mechanisms for adapting which beam to use for communicating signals. A method is performed by a radio transceiver device. The radio transceiver device is capable of communicating the signals using beams selected from a set of beams. The method comprises communicating signals with another radio transceiver device while using a first beam selected from the set of beams. The method comprises detecting that the signals are communicated at decreasing quality level while using the first beam. The decreasing quality level is caused by radio propagation channel deterioration. The method comprises, in response thereto, initiating a switch to a backup beam of the first beam, without performing any beam training, to continue communicating the signals with said another radio transceiver device, thereby adapting which beam to use for communicating the signals.

    Abstract: According to embodiments, a signal processing device includes an AD converter, a memory, a prediction logic circuit, an error amount detection circuit, and a selector. The AD converter converts an input signal to an AD conversion value at a certain sampling frequency. The memory stores an AD conversion output result. The prediction logic circuit predicts a prediction value by using the AD conversion output result at the sampling frequency. The error amount detection circuit determines that there is no error in error determination of the AD conversion value when an error amount between the prediction value and the AD conversion value is smaller than a predetermined amount, and that there is an error in the error determination when the error amount is equal to or larger than the predetermined amount. The selector outputs one of the AD conversion value and the prediction value as an AD conversion output result, on the basis of the error determination.

  • Patent number: 10454615
    Abstract: There is provided an ultra-light decoder for high speed digital communications based on block codes such as turbo product codes (TPCs). The new decoder can perform soft decision decoding without an algebraic hard decision decoder, which is the core of conventional soft decision decoders. The elimination of algebraic decoder significantly reduces the number of computations required per codeword, consequently, it reduces the decoding delay and processing power. However, reducing the decoding delay would immediately enable increasing the transmission speed, and minimize the need for large buffers at the receiver. Moreover, reducing the complexity and delay would enable using codes with high code rates to increase the system capacity, or use powerful codes with low code rates to reduce the transmission power. Such benefits can be achieved for about 1 dB loss in coding gain. There is also provided a receiver comprising the ultra-light decoder, as well as a decoding process.
