where [p.sub.T] is the real power or internal product of the voltage and current vectors and q is the imaginary

vector power or external product of the voltage and current vectors which is composed of [q.sub.[alpha]], [q.sub.[beta]], and [q.sub.0].

Garmin and MetriGear intend to bring the

Vector power solution to market.

ParkerVision is offering two families of RF power amplifier products - the

vector power amplifier (VPA) and digital power amplifier (DPA).

The EVM is defined as the square root of the ratio of the mean error

vector power to the mean reference power, expressed as a percentage:

The equation (56) includes not all complex scalar and vector powers of the complex form of the scalar (36) and vector (47) IP.

If to use a couple of sequences [{[U.sub.k]}.sub.k[greater than or equal to]1], [{[I.sup.*.sub.m]}.sub.m[greater than or equal to]1] then an additional equation for the complex scalar and vector powers which are not included in (56) is true.

Expansion of the square of the apparent power (52) taking into account (58), (59) gives an additional equation for the complex scalar and vector powers
