Filter Bank Multicarrier (FBMC) frameworks are a subclass of multicarrier (MC) frameworks. The essential guideline, separating spectrum into many thin sub channels, may not be new, MC frameworks have seen wide appropriation. These days, multicarrier regulation frameworks dependent on the discrete Fourier transforms are usually used to transmit over recurrence particular channels subject to forceful noise aggravations. In any case, these handsets experience the ill effects of poor sub channel spectral control, that is, the measure of inter channel impedance isn't unimportant. It very well may be indicated that the framework execution reduces when it is dependent upon an unsettling influence with a large portion of its energy focused on a narrow frequency band. This Paper aims that identify the Filter Bank Multi Carrier (FBMC) performance. The MIMO system combined with the FBMC then identifies the over Frequency Selective Channel (FSC). Here the analysis for FSC, Flat fading model FBMC and system with MMSE equalization. The Prototype filters are analyzing the system performance characteristics. The Power Spectral Density (PSD) of the MIMO FBMC system for the given spectrum. The proposed systems are best to compare all existing technique and we measure the spectral efficiency of the system.

A novel transform-domain speech bandwidth extension algorithm is proposed to transmit information about the missing speech frequencies over a hidden channel, i.e., the related encoded spectral envelope parameters are hidden within the narrowband speech signal using discrete wavelet transform-fast Fourier transform-based data hiding (DWTFFTBDH) technique. The hidden information is recovered reliably at the receiver to produce a wideband speech signal of much higher quality. Obtained results confirm the excellent reconstructed wideband speech quality of the proposed method over traditional methods.

Due to advances in high-speed data communication, packet classification plays a major role in computer networks to improve network security. Field Programmable Gate Array (FPGA) devices can be easily used for the packet classification process due to high speed and flexibility. Using FPGA high throughput is achievable when compared to the embedded devices. To enhance throughput, a novel pipelined FPGA design for packet categorization is discussed in this work.To evaluate the performance various metrics such as Look Up Tables(LUT), Flip Flops(FF), Area, and Power Consumption will be estimated and compared with conventional techniques for Various rule sets. On a Xilinx Ultra Scale FPGA, the proposed technique is implemented. The classifier’s throughput may exceed 802 million packets per second with less latency of 31 ns.

One of the most crucial thing to safeguard the network against malicious activities is security and the network devices must be able to classify packets. The firewall applications benefit greatly from the architecture of the packet classification engine that is given in this research work. A tree-based approach is used to systematically analyze each field in a packet header, leading to a more secure system. The Packet Classification Engine (PCE) is configured to evaluate Ethernet packets based on the source IP address, destination IP address, source port, destination port, and protocol aspects in the packet header. The PCE shows that the typical clock frequency from input to output is 13 clocks per second. The architecture is extremely rapid, reliable, and adaptable and can make good use of the tree based algorithm's advantages. The proposed architecture has achieved high throughput of 538 MPPS with less energy of 10.6 nJ at low latency of 62 ns. The PCE must have a rapid and reliable FIFO buffer to work effectively. A FPGA (Field Programmable Gate Array) device is being utilized to filter Ethernet packets using the proposed PCE.
