Near-Field Channel Estimation for Movable Antenna Systems: Angle-to-Distance Recovery via Movement Range Adjustment

Movable antenna (MA) is an emerging technology that enables flexible adjustment of antenna positions to fully exploit continuous spatial variations of wireless channels. As the antenna movement region expands, the available spatial degrees of freedom (DoFs) increase, motivating the use of large movement regions. Howeve...

Subband Precoding Optimization in OFDM–RSMA

In this paper, we study the optimization of subband precoder for an orthogonal frequency division multiplexing rate-splitting multiple access (OFDM-RSMA) system in a multi-user multiple-input single-output (MU-MISO) downlink scenario. In conventional OFDM-space division multiple access (SDMA) systems, each subband cons...
