A method to compensate the mutual coupling between array elements composed of multi-mode antennas and single-mode antennas has been proposed. By introducing a concept of an equivalent array spacing, the compensation can be achieved without using the

In cellular communications systems using digital radio services, especially those that use low-Earth orbiting satellites (LEOs), phase-modulated signals such as QPSK are received with relatively fast Doppler shifts. We developed a coherent detector w
