摘要: A multiuser communication system comprises multiple transmitters and a multiuser receiver that detects multiple transmissions via iterative soft interference cancellation. An initial acquisition module and single user decoder module are also described. The multiuser receiver acquires and subtracts known users in the residual signal before acquiring new users in the residual signal, which is performed iteratively until no new users are detected or a stopping criterion is met. To aid receiver acquisition, the transmitters insert discrete tones into the transmitted signals. These allow the multiuser receiver to obtain initial estimates of the frequency, time, gain, and/or phase offset for each user. To improve the quality of cancellation the receiver refines estimates of gain, time, frequency and phase offsets for each user after each iteration, and calculates time varying SINR estimates for each user. The multiuser receiver may be satellite based, may be a distributed receiver, or process users in parallel.

摘要: A communication system for sending small data message is disclosed in which a user node receives data from a remote application program which is sent as a message to a central application program executing on a central hub. The user nodes sends the message to an access node using a first radio interface and the access nodes forward the message to a gateway node which relays the message to the hub over a second radio interface. The system also includes composite nodes which either implement access node and gateway node functionality, or switch operational modes between access nodes and gateway node functions. The mode switching can be triggered based on proximity to access nodes, or by instructions from a hub. The gateway nodes can implement a message storage function, and can be implemented as software defined radios.
