Radio Communication Device and Arrival Direction Estimation Method |
摘要 |
A receiver having an array antenna (1) estimates arrival directions of multiple paths that arrive with an angular extension. Consequently, arrival direction estimation accuracy can be ensured without increasing throughput even if the power of every path is low by estimating an average arrival direction of an entire set of multiple paths having the angular extension from a result of one angular spectrum by multiple correlation operation units (4) that perform mutual correlation operations with pilot signals for baseband signals received by the array antenna, a path detection unit (6) that detects multiple arrival path receiving timings by generating a delay profile based on output of each of the correlation operation units, a path correlation value synthesis unit (7) that synthesizes a correlation operation value calculated in the multiple correlation operation units and an arrival direction estimation unit (8) that collectively estimates multiple path arrival directions using output of the path correlation value synthesis unit.
