METHOD FOR HIGH RATE AND LOW COMPLEX USER SCHEDULING USING INTERFERENCE ALIGNMENT IN MULTI-ANTENNA MULTI-TRANSMITTER MULTI-RECEIVER WIRELESS NETWORK

摘要

PURPOSE: A low-complexity scheduling method is provided to obtain a high transmittance and a maximum DoF(Degree of Freedom) through a linear interference alignment. CONSTITUTION: Each receiver perform a channel value feedback to each transmitter(501). Each transmitter estimates a necessary channel value(502). Each transmitter transfers the estimated channel value to a transmitter controller(503). Using the estimated channel value, an angle between a signal stream and an interference stream is obtained(504). A scheduling target receiver is successively selected one by one(505). A beam forming matrix about each receiver is calculated(507).
