SUMMARY This letter addresses a low‐complexity adaptive wireless data broadcasting system. Specifically, it proposes a way for reducing the computational complexity of the estimation process for the item demands, which in turn leads to a lower computational complexity to the broadcast server for selecting a data item to broadcast. We assume no a priori knowledge of the client demands for information items as happens in real environments. Simulation results reveal that the lowering of the computational complexity of the proposed system does not affect the performance offered to the system clients.
