WebDec 17, 2024 · OFDM (Orthogonal Frequency Division Multiplexing) 是一种多载波技术,常用于数据传输和无线通信领域。在 OFDM 系统中,信号被分成多个子载波,并在时域内并行传输。 OFDM 均衡方式包括: 1. 线性均衡:这种方式使用一个线性均衡器来减少多径反射造 … For comparison, we review the existing OFDM modulation technique, using the full occupied band, with the same length cyclic prefix. Comparing the plots of the spectral densities for CP-OFDM and F-OFDM schemes, F-OFDM has lower side lobes. This allows a higher utilization of the allocated spectrum, leading to … See more This example compares Filtered-OFDM modulation with generic Cyclic Prefix OFDM (CP-OFDM) modulation. For F-OFDM, a well … See more Define system parameters for the example. These parameters can be modified to explore their impact on the system. See more In F-OFDM, the sub-band CP-OFDM signal is passed through the designed filter. As the filter's passband corresponds to the signal's bandwidth, only the few subcarriers close to … See more Appropriate filtering for F-OFDM satisfies the following criteria: A filter with a rectangular frequency response, i.e. a sinc impulse response, meets these criteria. To make this causal, the low-pass filter is realized using a … See more name two spanish film festivals with at least
