Mobile station apparatus and signal detection and channel estimation method

Abstract

To cancel interference from the other cells and improve throughput characteristics without needing complicated processing, provided are a reception section that receives a reception signal including signal components from a plurality of base station apparatuses (BSs), and a signal detection and channel estimation section (61) that performs signal detection and channel estimation processing based on a factor graph on the reception signal, where the signal detection and channel estimation section (61) estimates interfering components from base station apparatuses of the other cells except a desired base station apparatus included in the reception signal at a symbol level, and reuses the interfering components in the signal detection and channel estimation processing based on the factor graph.

Dependencies are inferred from the claim text.
