In the uplink multiple access, the present invention utilizes the gain division multiple access (GDMA) technology to allow multiple users to share the same resource by utilizing the knowledge of different channel coefficients (channel gains) to distinguish signals transmitted by different users when the transmissions are over different and independent fading channels. Without using pilot signals for channel estimation, the present invention uses the clustering algorithm and the geometrical configuration of the superimposed signals for the superimposed signal sequence received by the base station to implement the estimation of channel gains corresponding to multiple users, and, according to the estimated channel gains, the GDMA technology is utilized to recover the original message transmitted by each user."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Communication system and method","description":"A communication system and method is disclosed, applicable to the mobile communication using pilot-free channel estimation.
