  • Patent number: 10931492
    Abstract: A method and apparatus for communication, e.g. in an LTE system, that uses two tones with an in-phase pi/2 BPSK modulation with single carrier frequency-division multiple access (SC-FDMA). Pairs of input bits are converted to symbols using pi/2 BPSK, with each one of the pair of bits converted using a same symbol constellation, and successive pairs of bits converted using alternatingly different symbol constellations. The two constellations may be identical after a pi/2 radian rotation. Pairs of symbols corresponding to pairwise converted bits may be treated as the symbols for a pair of tones of a subsequent SC-FDMA, OFDMA, or similar processing operation.

  • Patent number: 10841227
    Abstract: Datalink frames or networking packets contain protocol information in the header and optionally in the trailer of a frame or a packet. We are proposing a method in which part of or all of the protocol information corresponding to a frame or a packet is transmitted separately in another datalink frame. The “Separately Transmitted Protocol Information” is referred to as STPI. The STPI contains enough protocol information to identify the next hop node or port. STPI can be used avoid network congestion and improve link efficiency. Preferably, there will be one datalink frame or network packet corresponding to each STPI, containing the data and the rest of the protocol information and this frame/packet is referred to as DFoNP. The creation of STPI and DFoNP is done by the originator of the frame or packet such as an operating system.

The method may include conveying the data stream through a multi-level data channel and inspection architecture. The architecture includes a multi-level data pipeline. The pipeline is formed from pipes arranged serially such that each output of one pipe provides an input to a successive one of the plurality of pipes. The pipeline receives the data stream at an upstream portion of the pipeline, and inspects the data in the data stream. Thereafter, the pipeline outputs inspected data at a downstream portion of the pipeline. The outputted inspected data becomes inputted date for a successive one of the pipes. A data manager may be configured to coordinate passage of the data into and out of the pipeline, and between one or more of the group of mechanisms.
