  • Patent number: 10715207
    Abstract: A Global Navigation Satellite System (GNSS) receiver demodulates code shift keying (CSK) data utilizing correlations with combinational pseudo-random noise (PRN) codes generated for different bit positions. The GNSS receiver receives a signal including a PRN code modulated by CSK to represent a symbol (i.e., CSK modulated symbol). The GNSS receiver maintains a plurality of receiver codes, each representing a different shift in chips to the PRN code. The GNSS receiver performs a chip-by-chip linear combination of a group of receiver codes for each bit position of the CSK modulated symbol. The GNSS receiver correlates the received signal with each combinational PRN code to produce a binary value that is the CSK modulated symbol.

  • Patent number: 10644771
    Abstract: A system and method for increasing the capacity of a Multiple-Input Multiple-Output (MIMO) system at desired user's locations and reducing the capacity at locations, other than that of the desired user, while also providing secrecy. Knowing the channel coefficient between each transmitter and receiver antenna pair at the transmitter, the method of the present invention calculates the artificial signal that minimizes the Euclidean distance between the desired and received data symbols if the precoding/combining matrix pair from the set that has the minimum Euclidean distance to the singular value decomposition (SVD) of the channel matrix is used for transmission and reception. The artificial signal may be fed to the precoder, instead of the actual desired data symbols, or may be transmitted directly to reduce computational complexity, power consumption and processing delay if the hardware configuration allows.

  • Patent number: 10644869
    Abstract: A phase lock loop (PLL), such as an all digital phase lock loop (ADPLL) to provide an example, of the present disclosure operates in a frequency tracking mode to adjust a frequency of the output signal to be proportional to a frequency of a reference input signal, or, in a phase tracking mode to adjust a phase of the output signal to match any variations in the reference input signal. The ADPLL includes a phase and/or frequency detector that provides an error signal representing a difference, in frequency and/or phase, between the output signal and the reference input signal. The ADPLL monitors a trend of the error signal, such as a positive trend, a negative trend, or a flat trend to provide some examples, and switches among the frequency tracking mode and the phase tracking mode upon detecting a change in the trend of the error signal.
