Effective Channel Gain Estimation in cellular wireless networks

Interferences in cellular wireless networks (CWN) between central station (CS) and the terminal station (TS) have a direct impact on available throughput and represents the main capacity limitation, especially in networks with full frequency reuse among all CSs. More and more attention is being focused on a way of minimizing interferences. We are introducing a new Coordinated Channel Gain Estimation (CCGE) method, which dynamically estimates the channel characteristics such as path loss, shadowing and fading, often also referred to as channel gain (CG) between each TS and CS on backhaul point-to-multipoint (PMP) OFDMA-based CWN. The method is usable for smart CSs synchronization where CSs run in the cooperative mode to avoid interferences. We performed five different simulations, with the results displaying extremely good CG estimation.
