METHOD AND APPARATUS FOR PERFORMING INTERFERENCE ESTIMATION |
摘要 |
The present invention relates to a method and apparatus for performing an interference estimation in a spread spectrum system using a plurality of spreading codes with different code lengths, wherein the interference estimate is obtained based on a variance estimate of despread samples integrated over a predetermined code period over which said plurality of spreading codes are orthogonal. Thereby, an unbiased interference estimation with high accuracy and proper consideration of code orthogonality can be obtained.
