ZERO FORCING TRANSMISSION BEAM FORMATION METHOD USING A SEQUENTIAL ORTHOGONAL PROJECTION COMBINATION ALGORITHM, CAPABLE OF TRANSMITTING INFORMATION BY USING A FORMED TRANSMISSION BEAM, AND AN INFORMATION TRANSMISSION METHOD USING THE SAME

摘要

PURPOSE: A zero forcing transmission beam formation method using a sequential orthogonal projection combination algorithm and an information transmission method using the same are provided to remarkably reduce complexity by using the structure characteristics of a zero forcing beam moderated in an MISO(Multiple Input Single Output) IC(Interference Channel) environment.;CONSTITUTION: A Vk is initialized(S100). The Vk is assigned to a first expression(Vk + τ · VSOP)(S110). The existence of terminal I which is satisfied with a predetermined element is determined(S120). When terminal exists, the Vk is updated to a predetermined value(S130). When the terminal does not exist, the satisfaction of a second expression(¦¦Vk¦¦2 = Pk) is determined(S140). When the second expression is satisfied, the Vk is determined as a transmission beam(S150).;COPYRIGHT KIPO 2013;[Reference numerals] (S100) Initializing step; (S120) Is there a terminal I satisfying ¦¦h^H_lk V_k¦¦^2= α_lk σ^2_l in the elements of I_k; (S130) Updating step; (S150) V_k as a transmission beam
