Abstract: Embodiments of the present invention include methods and systems for detecting a peak of an ultra-wide-band (UWB) signal in a data stream. The system (1100) for detecting a peak of an ultra-wide-band (UWB) signal (1120) in a data stream (102) includes: one or more processors (1001); and a non-transitory computer-readable medium or media (1002) comprising one or more sequences of instructions which, when executed by the one or more processors (1001), causes steps to be performed comprising: selecting a portion (104) of a data stream (102) in a current clock cycle, the portion (104) of the data stream includes a preset number of data samples; finding a set of data samples included in the preset number of data samples, the set of data samples includes one or more consecutive data samples and has a uniform magnitude; and promoting the set of data samples as a peak if the uniform magnitude is higher than a magnitude of a first data sample that immediately precedes the set of data samples and a magnitude of a second data sample that immediately follows the set of data samples.

Abstract: An ultra low power, low complexity, low collision, deterministic modulation method that also works as a massive medium access mechanism for communication systems is based on positioning data in a communication resource space, such as time and frequency, such that the position of a symbol in that space determines its value and its access to the medium. The number base of the symbol is determined by the size of the subset of the resource space it is positioning itself in and, thereby, a few sparsely located symbols can convey a large value, while the remainder of the space can be simultaneously and massively used by other sparsely resource using members of the network.

Abstract: An asymmetric bandwidth communication system enables wireless communication between interrogators/ readers and transponders/ tags. A transponder transmits TDCIR (Time Domain Carrierless Impulse Radio) signals in the uplink direction and receives non-TDCIR signals, such as electromagnetic continuous waves, in the downlink direction. The transponder may receive partial or whole power from non-TDCIR signals. The TDCIR utilizes electromagnetic impulses with short duration and ultra wide bandwidth. It offers high data rate reliable communication at low power and design complexity. It also demonstrates resilience against path fading, selective absorption and reflection by physical matters and excellent location determination capabilities.
