On the Reliability of Spread FBMC Wireless Sensor Networks for Off-Tone Jamming

Abstract

In this paper, the reliability of spread Filter Bank Multicarrier (FBMC) Wireless Sensor Networks (WSNs) is analyzed for several off-tone jamming techniques to obtain a performance measure under intentional and unintentional interference. It is shown that FBMC is more robust against jamming signals with high Carrier Frequency Offset (CFO) than conventional Orthogonal Frequency Division Multiplexing (OFDM). Moreover, FBMC with Frequency Spreading (FS) shows a better performance than Multicarrier Code Division Multiple Access (MC-CDMA) when both are spread with a Walsh-Hadamard (W-H) code. When Time Spreading (TS) is applied, spread FBMC mostly outperforms MC-Direct Sequence (DS)-CDMA in terms of Bit Error Ratio (BER). A higher throughput can be also achieved when spread FBMC is implemented.
