ABSTRACT
Heterogeneous networking seems to be a viable option for extending wireless coverage, reducing congested bandwidth, and improving system performance in next-generation wireless networks. Furthermore, interference between overlay cells is one of the most difficult issues to overcome when deploying heterogeneous networks. Short-period interference is created by femtocell uplink broadcasts involving macrocell users. This is shown by the fact that femtocell networks suffer significant performance degradation when utilizing OFDMA or SC-FDMA protocols that lack information on the interferer channels that link macrocells and femtocells to the base station. Consider employing precoded FDMA (P-FDMA) transmission to novel detectors to prevent shot interference. The PFDMA strategy may maximize overall signal intensity in any receive antenna and throughput for many receive antenna systems by using a multi-stream transmission. Our suggested 72structure accumulates multipath variety in the presence of interference to the knowledge of interferer channels, according to the findings, and our concepts seem to be dependable on incursion power levels. Simulation evidence backs up our theoretical results..
