MIMO-ISS Waveform System

MIMO-ISS Waveform System is a “non-linear” digital communications, modulator-demodulator (i.e. modem) waveform system. Mathematically, the modem system operates based on the concepts and principles of “non-linear”, digital modulation theory.

The MIMO-ISS Waveform System introduces two “innovative” non-linear modulation concepts. These non-linear modulation concepts are:

Intermodulation Spread Spectrum (ISS) is a state-of-the-art, non-linear, angle-modulated spread spectrum digital modulation technique. Additionally, the ISS waveform is a constant-envelope and multi-dimensional wideband digital spread spectrum waveform system. ISS enables advanced digital communications systems that offer high immunity to interception, detection, and jamming. And lastly, ISS enables next-generation digital communications systems that offer high power efficiency, high spectrum efficiency, and high system capacity.

The target application areas for the MIMO-ISS Waveform System are next-generation (1) cellular radar and (2) cellular networking markets.

MIMO-DPR Radar System

MIMO-DPR Radar System is a “non-linear” digital radar system. The key architectural component of the MIMO-DPR System is a concept called “active” plenoptics. “Active” plenoptics is the integration of code division multiple access (i.e. CDMA) techniques with the discrete geometry algorithms into a new concept of radar systems.

Plenoptics is a concept adapted from computational photography. The word plenoptic is derived from Latin. Plenoptic means "full image" or "full vision". As such, the concept of digital plenoptic radar translates as follows:

As an integrated component of the MIMO-ISS System, MIMO-DPR operates using the Intermodulation Spread Spectrum (i.e. ISS) modem waveform system. In combination with the ISS waveform, these concepts enable advanced geometric digital radar systems that operate with high immunity to interception, detection, and jamming. Operationally, the MIMO-DPR Radar System enables improved detection, ranging, and parametric operations of the radar system.

The target application area for the MIMO-DPR Radar System is next-generation automotive radar markets.

MIMO-CRN Networking System

MIMO-CRN is a “non-linear” digital cellular networking system. The MIMO-CRN System is a distributed cellular “and” radar networking system. MIMO-CRN offers significant advancements in the system’s time and spatial synchronization architectures, waveforms, protocols, and algorithms. The MIMO-CRN System architecture is based on the cellular single-frequency networking (SFN) concepts. Cellular SFN technology represents the most state-of-the-art networking paradigms and concepts to enable distributed cellular “and” radar networking applications.

The MIMO-CRN system supports integrated mobility, as well as, serves as a building block for future urban societies, where autonomous vehicles, smart homes and infrastructure synergistically cooperate to create “smart” cities. In support of high-density networking (i.e. densification), MIMO-CRN provides synergistic operations, radar detection, and communications within (intra-system) and between (inter-system) systems of smart nodes.
