Company Objective

Moriah Technologies Inc.'s performs research, design, and development of innovative signal processing systems for advanced digital communication devices, software, and systems.


Company Profile

Moriah Technologies, Inc. specializes in the research and development of advanced digital communication algorithms, techniques, and systems. The Company has developed two innovative, advanced, and proprietary digital communications techniques referred to as Coherent Angle Modulation Spread Spectrum and InterProduct Exponential Codes.

 

 

Coherent Angle Modulation Spread Spectrum

Coherent angle modulation spread spectrum (CAMSS) is accomplished through the use of three advanced modulation building blocks. They are:

  • Coded Intermodulation Multiple Access (CIMA)

  • Intermodulation Waveform Shift Keying (IWSK)

  • Multi-Dimensional Symbol Multiplexing (MDSM)

Coded Intermodulation Multiple Access (CIMA) is an MDSM-based, constant-envelope, digital angle modulated multi-user, code division multi-access scheme. The major advantage offered by this modulation scheme is that it provides an increase of system capacity through a system processing gain that is linearly proportional to the ratio of the RF bandwidth to the information rate. Secondly, CIMA uniquely allows "multiple MDSM" users to simultaneously share and access the same communications channel at the same time and at the same frequency.

 

Intermodulation Waveform Shift Keying (IWSK) is an MDSM-based, constant-envelope, digital angle modulated data transport technique. The major advantage offered by this technique is that it provides a system processing gain that increases non-linearly in proportion to the bandwidth expansion. This feature enables the development of systems that provide high capacity data transmission rates, and that have extremely high immunity to intentional and unintentional interference. A second key advantage is that it eliminates the high peak-to-average power ratio problem inherent to present-generation MDSM systems, thereby enabling systems that offer improved operating performance and that are more power, cost, weight, and size efficient.

 

 

Multi-Dimensional Symbol Multiplexing (MDSM) is an innovative multi-dimensional "data transport" and "codeword" symbol encoding technique. In the CAMSS signaling system, the MDSM symbols define a waveform-based, block-oriented data symbol set. This waveform-based MDSM symbol increases the receiver immunity to channel interference, noise, and multi-path effects.

 

InterProduct Exponential Code

InterProduct Exponential Coding (IPEC) is an advanced and innovative non-binary forward error correction coding technique. InterProduct Exponential Codes are implemented as systematic, cyclic block codes. In the IPEC encoding system, non-binary bit groups are converted into a set or system of tightly coupled, interdependent linear algebraic equations. The coupling and interdependency relationships introduces a "graphical circular" memory component into the encoding process of the codeword. The IPEC forward error correction system supports the “optimum” implementation of high data rate, bandwidth-efficient, and power-efficient communications of data.
