Patent number: 7352721Abstract: A joint channel and Direction of Arrival (DOA) estimation apparatus and method simplified to efficiently estimate a channel impulse response associated with a spatially selective transmission channel occurring in a mobile radio channel are provided. To uniformly process all directions, angles associated with a beam are predetermined according to a preset method. This selection calculates a linear system model with regular spatial sampling using regular spatial separation of beam angles. The novel beam forming compensates for a difference between an adaptive array antenna and a sector type antenna using appropriate beam steering according to the calculated linear system model, thereby improving performance and facilitating implementation.Type: GrantFiled: May 6, 2005Date of Patent: April 1, 2008Assignee: Samsung Electronics Co., Ltd.Inventors: Byoung-Yun Kim, Song-Hun Kim, Katz Marcos Daniel, Seong-Ill Park, Tobias Scholand, Peter Jung, Achim Seebens, Ar jang H.

Patent number: 7342535Abstract: A beam-forming apparatus and method for improving system performance using a spatial interpolation and at least one Angle of Arrival (AoA) in a system based on regular spatial sampling is provided. The AoA is estimated using a carrier-to-interference ratio. Beam-forming angles are distributed and steered in a predefined scheme such that an identical process is applied in all directions. According to this steering, a linear system model is computed based on regular spatial sampling using regular spatial separation at beam angles. Beam-forming performance is improved by compensating for a difference between adaptive and sector-type arrays. Only the steps of computing a spatial interpolation and determining an angle range for beam-forming using at least one AoA are added. The precision of estimating an AoA and the precision of beam-forming increase without an additional antenna. Because the system is simpler than that of an adaptive beam-forming system, significant gain is obtained.Type: GrantFiled: April 7, 2006Date of Patent: March 11, 2008Assignee: Samsung Electronics Co., Ltd.Inventors: Jong-Hoon Ann, Song-Hun Kim, Byoung-Yun Kim, Hye-Young Lee, Hyeon-Woo Lee, Achim Seebens, Tobias Scholand, Peter Jung, Admir Burnic, Arjang Hessamian-Alinejad
