An important problem of the adaptive array antenna proposed previously in regard to its installation is the increased equipment size. This is because the adaptive array antenna requires as many RF circuits as the number of antenna elements. In this p

A frequency domain equalization for multipath fading is widely used for OFDM systems and accurate channel estimation is required. In conventional OFDM systems, pilot symbols are inserted periodically in time and frequency domain by a transmitter for

A tapped-delay-line adaptive array antenna (TDL-AAA) is proposed for the method of space and temporal (frequency) equalization. However, this method has a drawback that requires many variable taps (AAA elements /spl times/ LE (linear equalizer) taps)
