“…To evaluate the performance of the developed two-stage channel estimation technique, we examine its performance as applied to a filter-bank multicarrier spread-spectrum (FBMC-SS) waveform in HF channels. We use the FBMC-SS waveform for its demonstrated robust performance at low-SNRs; e.g., [29], [30]. Similarly, we study the performance in HF channels because they are both doubly-dispersive and sparse in delay [2], and therefore pair well with the proposed channel estimation technique.…”

Using pilot-symbol assisted modulation, we develop a method to acquire channel information from signals received in low-SNR environments. First, we estimate the power-delay profile (PDP) of the channel. Then, we apply information from that estimate to obtain the channel coefficients only at points where the PDP is nonzero. Because we estimate a reduced number of channel coefficients, the complexity and estimation error are simultaneously reduced. We present a case study of the proposed estimation method when applied to a wideband skywave high frequency (HF) channel. Through this study, we find that the proposed approach has significantly enhanced performance when compared to an existing method that does incorporate sparsity information into its estimate. The improved low-SNR performance of the proposed estimator makes it particularly well suited for spread-spectrum and underlay waveforms.

“…The applicability of FBMC modulation for high-frequency (HF) channels was introduced in [ 5 ] with the addition of the spread-spectrum (SS) technique, and the robustness of the introduced modulation technology was proved for channels with low SNR values and a wide range of Doppler spread and delays. Further, the same authors in [ 6 , 7 ] provide theoretical and practical comparisons of the FBMC-SS system and Walsh sequence-based direct sequence spread systems (DSSS). The same authors in [ 8 ] presented an analysis of FBMC-SS performance in doubly dispersive HF channels and showed methods of system parameter optimization to reduce the influence of doubly dispersive channel distortions.…”

Increasing the data transfer rate is an urgent task in cellular, high-frequency (HF) and special communication systems. The most common way to increase the data rate is to expand the bandwidth of the transmitted signal, which is often achieved through the use of multitone systems. One such system is the filter bank multicarrier (FBMC). In addition, speed improvements are achieved using multi-input–multi-output (MIMO) systems. In this study, we developed an algorithm for equalizing FBMC signals with offset-QAM modulation (OQAM) with self-interference compensation due to its correlation properties in a MIMO channel with memory. An analytical derivation of the proposed algorithm and an analysis of the computational complexity are given. According to the results of simulation modeling and a comparative analysis of performance in terms of the bit error rate and error vector magnitude with solutions with similar computational complexity, a similar level of performance was shown compared to a more complex parallel multistage algorithm, and a better performance was demonstrated compared to a one-tap algorithm.
