“…Filterbank-based MC-CDMA (FB-MC-CDMA) schemes have been studied in single antenna systems. These systems were first proposed in (Liu 2004) and (Bianchi 2004) and further studied in (Wang 2014, Van Bolo 2017, where the performance of different FB-MC-CDMA systems in the presence of CFO is studied. Further studies show that different digital implementations of MC-CDMA can overcome the flaws of the polyphase decomposition-based fast algorithm (Gao 2006, Bian 2018, Reena raj 2021, Wang 2022.…”

Filterbank multicarrier (FBMC) is an effective method for modulation over massive multiple-input multiple-output (MIMO) channels in the future fifth generation wireless networks. This multicarrier technique provides high spectral efficiency, and it is resilient against synchronization errors compared to the well-known orthogonal frequency division multiplexing technique. This paper introduces a new technique, that combines the Code-division multiple-access (CDMA) and cosine modulated filter banks, a specific class of FBMC, to massive MIMO communication systems. In the proposed technique, the data symbols are transmitted on different sub-bands and also, they are spread in each sub-band by CDMA code. The proposed technique reduces the interference between data symbols, which consequently improves bit-error-rate (BER) performance. Simulation results show that the overall BER performance of the proposed multicarrier transmission technique is significantly enhanced. The results obtained show that as the number of base station antennas increases, different channel distortions are averaged out, thus BER decreases (in average by 10–2) for the same signal-to-noise ratio.

“…Currently, Spread Spectrum techniques have been widely used in many communication systems [6] such as GLOBALSTAR satellite communications system [5], Low Earth Orbiting (LEO) satellite communications network systems [7], GPS for satellite navigation system [8], Wireless Local Area Networks (WLAN) IEEE 802.11 system [8], optical codes for Fiber-optic Local Area Networks (LAN) [9], digital cellular radio system IS-95 for mobile voice communication [8], Wideband-CDMA for third-generation mobile communication system [8], wireless communication and control systems in Unmanned Aerial Vehicles (UAV) [10], underwater acoustic communication system [11]. This spread spectrum system is now developed for multiple access techniques on fifth generation (5G) cellular telecommunication system [12]. Spread Spectrum systems have been used in many other applications such as digital watermarking for copyright protection of audio, image and video, and multimedia data [13]- [15], digital watermarking for telemedicine [16], DC / DC converter circuit [17], LLC Resonant [18], and 3rd Generation Attachment Series (SATA-III) for reducing electromagnetic interference (EMI) problems [19].…”

This paper presents performance evaluation and comparison analysis of Direct Sequence Spread Spectrum (DSSS) and Frequency Hopping Spread Spectrum (FHSS) systems. The evaluation and analysis are done based on the systems performance against wideband interferences. The interferences are signals with similar spectrum characteristic to the transmitted signals of DSSS and FHSS systems. Bit Error Ratio (BER) is used as evaluation parameter to assess the performance of both systems. Simulation and mathematical analysis are performed to test and verify the performance of both systems. Mathematical analysis also verifies that increasing Spreading Frequency on certain conditions will reduce the BER. This research also points out that FHSS system has a better performance compared to DSSS system indicated by smaller BER.
