Deterministic Pilot Design for Sparse Channel Estimation in MISO/Multi-User OFDM Systems


We study the pilot design problem for sparse channel estimation in OFDM systems where multiple channels are estimated at a single antenna receiver. Such design is applicable to downlink of massive-MIMO systems and also to scenarios where multiple users transmit to a base station at the same carrier frequency. In our design, we deviate from the conventional… (More)
