A network based blind approach to optimizing multi-receiver system performance

In cellular networks, signals from a single transmitter are generally observed by multiple distributed receivers. For such a network, we propose a training-free network based processor or "quality of service manager" (QM) which operates autonomously to optimize network performance by guaranteeing a pre-specified level of bit error rate (BER) performance while simultaneously maximizing throughput. This goal is achieved by dynamically adapting the channel code used by the transmitter based solely on the bit decisions of networked receivers. The scheme requires no change to the existing setup and requires the addition of only a limited capability processor, the QM, to optimize network performance. We show, via simulations, that in situations where the existing approaches fail to guarantee quality of service (QoS), the QM not only guarantees QoS but also results in multiple times throughput.
