The Communications-Electronics Command (CECOM) is a Life Cycle Management Command (LCMC) of the United States Army based at Aberdeen Proving Ground, Maryland, United States. It is one of four such commands under the Army Materiel Command (AMC), and is the Army's provider and maintainer of Command, Control, Communications, Computers, Cyber ...
It enhances command and control of tactical units by providing commanders with the location of friendly units. [2] It was first fielded by the US Army in 1987. [3] EPLRS is a Time Division Multiple Access System that uses a frequency hopping, spread spectrum waveform in the UHF band. [4]
[4] It conducts and sponsors scientific research in areas important to the Army, develops scientific discoveries into new technologies, engineers technologies into new equipment and capabilities, and works with the U.S. Army Training and Doctrine Command to help requirements writers define the future needs of the Army.

The CM is a joint initiative to upgrade the DoD crypto inventory. Of the 1.3 million cryptographic devices in the U.S. inventory, 73 percent will be replaced over the next 10 to 15 years [when?] by ongoing and planned C4ISR systems programs, Information Technology modernization initiatives and advanced weapons platforms.

The Hadamard product operates on identically shaped matrices and produces a third matrix of the same dimensions. In mathematics, the Hadamard product (also known as the element-wise product, entrywise product [1]: ch. 5 or Schur product [2]) is a binary operation that takes in two matrices of the same dimensions and returns a matrix of the multiplied corresponding elements.
5 is halved (2.5) and 6 is doubled (12). The fractional portion is discarded (2.5 becomes 2). The figure in the left column (2) is even, so the figure in the right column (12) is discarded. 2 is halved (1) and 12 is doubled (24). All not-scratched-out values are summed: 3 + 6 + 24 = 33. The method works because multiplication is distributive, so:
Though the multiply instruction became common with the 16-bit generation, [4] at least two 8-bit processors have a multiply instruction: the Motorola 6809, introduced in 1978, [5] and Intel MCS-51 family, developed in 1980, and later the modern Atmel AVR 8-bit microprocessors present in the ATMega, ATTiny and ATXMega microcontrollers.
In combinatorics, the rule of product or multiplication principle is a basic counting principle (a.k.a. the fundamental principle of counting). Stated simply, it is the intuitive idea that if there are a ways of doing something and b ways of doing another thing, then there are a · b ways of performing both actions.
