HYBRID MULTIUSER INTERFERENCE CANCELLATION METHOD USING DYNAMIC PROGRAMING-BASED GROUPING TECHNIQUE AND APPARATUS THEREFOR

摘要

PURPOSE: A hybrid multiuser interference cancellation method using a dynamic programming-based grouping technique and an apparatus therefor are provided to prevent the deterioration of detection performance due to a signal power difference by forming at least a group so that each of the received user signal power differences can be minimized. CONSTITUTION: A hybrid multiuser interference cancellation apparatus(300) comprises a channel estimator(301), a sorting part(302), a cluster calculator(303), and a hybrid interference canceller(304). The channel estimator(301) discriminates use signals from a plurality of signals received from the external and calculates the power of each of the discriminated user signals. The sorting part(302) arranges the calculated user signal power in the order of a descending series. The cluster calculator(303) forms more than a group through a dynamic programming-based grouping technique using the sequential numbers based on the arranged user signal power.
