Abstract

To generate multiple access signals, each transmitter transmits signals by using all or part of channel resources. The signal of each transmitter is mapped to the OFDM time-frequency resource space as a trellis modulation path. The mobile communication system maps the trellis modulation paths of multiple transmitters to the same resource space. In order to efficiently detect and distinguish signals of multiple transmitters transmitted through the same channel resource space, a receiver uses a message passing method between symbols and a path connection method. The receiver uses state space expansion method, backward pre-decoding method and successive interference cancellation method to reconstruct the discovery signal more efficiently.

Description

technical field [0001] The present disclosure relates to a mobile communication system, and more particularly to a method and apparatus for generating / reconstructing a multiple access signal. Background technique [0002] Mobile communication systems are widely configured to provide various types of communication. For example, voice and / or data may be provided over a mobile communication system. A typical mobile communication system or network may provide multiple users with access to one or more shared resources. [0003] In general, multiple access in a mobile communication system refers to a method in which a plurality of transmitters transmit signals within the same area with a limited frequency band by using the same transmission medium, and the transmission of the transmission medium is shared by multiple access capacity. Multiple access techniques are broadly classified into two methods. Contents of the invention [0004] technical problem [0005] The first me...
