Iterative demodulation and channel estimation for joint random access satellite communications

Posted May 21, 2015

Dickson, P., Schlegel., C. 2014

Future high-density multiple-user interactive satellite communications is investigated by proposing advancements in receiver design for random access on the uncoordinated satellite up-link. Joint detection and multiple packet reception (MPR) techniques are applied to show that it is possible to surpass the capacity of the current single-user random access channel. This is accomplished through adaptation of the concept of generalized modulation and the use of iterative estimation coupled with advanced interference cancellation techniques.
