WebJun 4, 2014 · This paper compares FBMC receiver architectures, providing performance and complexity analysis, based on closed form expressions and on an actual implementation. Polyphase network (PPN-) and frequency spreading (FS-) FBMC receiver structures are discussed. The FS-FBMC structure is selected for hardware implementation and … WebThe goal of employing a polyphase network (PPN) in FBMC guarantees that FBMC has the same FFT size and complexity as OFDM to compensate for the complexity of using Hermitian symmetry. Even though FBMC could …
