Joint Communication and Jamming System Design Based on Filter Bank Multicarrier Chirp Waveform: Using for Curvilinear Flight Scenario
نویسندگان
چکیده
A joint communication jamming waveform is proposed in this study based on the FBMC- chirp. To increase number of false targets a single pulse period, chirp signal modulated to different subcarrier groups. Since subcarriers FBMC-OQAM are orthogonal, signals naturally orthogonal. This allows transmitter and receiver be separated achieve multiple target jamming, allowing CFAR threshold raised by about 20 dB protecting from detection. The ratio frequency shift designed modulation depends delay time, making more robust response resistant modulation. use intercepted radar allowed channel estimation, providing high-speed digital transmission while ensuring multi-false-target jamming. simulation results show that has effects Doppler radar. FBMC requires less than existing method, thus energy saved can ensure performance subsystem system. system excelled rate bit error performance, instructions accurately completely transmitted implementing effective

Filter Bank – Based Multicarrier Modulation
Even though we do have on going research on traditional OFDM/DMT techniques, part of our research in multicarrier communication concentrates on filter bank-based multicarrier modulation. We refer to this as cosine-modulated filter bank multicarrier modulation (CMFB-MCM) or cosine-modulated multitone (CMT), for a shorter terminology. In the past, under the name discrete wavelet multitone (DWMT) ...
متن کاملLMS-based Equalization in Filter Bank Multicarrier Wireless Communication Systems
Multicarrier systems give many attractive characteristics for high data rates wireless communications. Filter bank multicarrier systems (FBMC) provide some advantages more than the traditional orthogonal frequency division multiplexing (OFDM) with cyclic prefix (CP). The most obvious difference between the two techniques is in frequency selectivity. In this paper, we will design adaptive channe...
متن کاملPreamble-based frequency-domain joint CFO and STO estimation for OQAM-based filter bank multicarrier
Filter bank multicarrier systems, similarly to orthogonal frequency division multiplexing (OFDM), are very sensitive to carrier frequency offset (CFO) and symbol timing offset (STO). In this paper, a low-complexity preamble-based joint CFO and STO technique is presented. It is based on a relatively long preamble in order to improve the CFO estimation performance as well as avoid interference co...
متن کاملSpecification and design of a prototype filter for filter bank based multicarrier transmission
The specifications of filter banks for multicarrier transmission systems with a large number of subchannels are discussed, with application to xDSL and power line communication in mind.The near PR modulated approach is considered and the importance, for the system, of the protype filter delay is stressed. An existing design technique known to be particularly relevant to the context is revisited...
متن کاملDesign of Optimal Filter Bank for Multicarrier Modulation Systems
Spectral efficiency is the key factor for the development of future wireless communications. Recently, filter bank multicarrier (FBMC) modulations have attracted a lot of attention due to capability to efficiently cope with frequency selective channels. Much of the attention in the present literature emphasizes on the use of conventional orthogonal frequency division multiplexing (OFDM). Howeve...
