Abstract:
An arrangement comprising:K multipliers, each responsive to a symbol to be transmitted and to a distinct weighting factor &ngr;i forming a vector v; and K transmitting antenna, where transmitting antenna i is coupled to multiplier i of said K multipliers; where K is an integer greater than one, the weighting factor vector, v, is proportional to v=(gH)H, H is a matrix of channel transfer coefficients hpq, p=1,2, . . . K, and q=1,2, . . . L, subscript 4 designates the Hermitian operator, L is an integer that corresponds to the number of antennas of a receiver, and g is a vector of L components, such that (gp&it;gq*)=&Sum;k=1K&it;hp&it;â€ƒ&it;k&it;hq&it;â€ƒ&it;k*&LeftBracketingBar;&Sum;k=1K&it;hp&it;â€ƒ&it;k&it;hq&it;â€ƒ&it;k*&RightBracketingBar;.
