Title:
OFDM RECEIVER USING ADAPTIVE ARRAY
Document Type and Number:
Japanese Patent JP2002232386
Kind Code:
A
Abstract:
To provide an OFDM receiver in which deterioration due to multipath is resolved by eliminating interference wave by using adaptive array signal processing.
Regarding an OFDM signal which is received with a plurality of antennas and contains a pilot symbol, a norm to a regular signal point is calculated from the received pilot symbol extracted after FFT. On the basis of the result, the arriving direction of an arriving signal is estimated, and a reference signal of an adaptive array is formed in only a guard interval. The optimum weight coefficient is calculated by using MMSE, and updated every OFDM symbol, thus performing the adaptive array signal processing.
