PURPOSE:To provide an accurate demodulated signal from a CDMA(code division multiple access) received signal. CONSTITUTION:When a base band signal (r) is received, at an interference removing part 4, first-stage estimate signals for M pieces of stations provided while removing an inter-station interference amount at an interference removing means 41-1. Next, the inter-station interference amount is removed from the first-stage estimate signals by an interference removing means 41-2 and estimate signals further for M pieces of stations are provided. Thus, final estimate signals (symbol estimated values) t-1 to t-M for M pieces of stations are outputted by an interference removing means 41-K on a K-th stage. |
