Abstract - The input signal has a great influence on the performance of the system in digital control system. Processing of input signal is important to get useful signal. In the processing of digital signal Finite impulse response (FIR) filter plays an important role. Using Matlab the FIR filter is designed and simulated. Different methods like frequency sampling, window function and convex optimization technique are processed using Matlab in the design of FIR filter. By comparing the signal’s amplitude-frequency diagrams which have been generated the filtering effect of different digital filters are analyzed by using FIR digital filters which are designed to process the input signal based on the Matlab function. This paper shows the experimental results show the FIR filters designed.

Abstract - In wireless communication networks, a number of researchers planned to take apart a single shared channel into numerous sub-channels: one as direct sub-channel and the others as data sub-channels [1]. Aloha is feasibly the simplest and most-studied medium access control protocol in existence. Earlier study on OFDMA aloha has shown that the usage trend analysis very much depends on the performance of the multiple channel schemes. But this algorithm has some disadvantage: It may not develop the throughput performance of a MAC scheme [3], [4]. The first drawback does not only concern aloha, but all other algorithms. In this paper, we will analyse a scheme with ns2 to enhance the performance analysis of the medium access control (MAC) mechanism using IEEE 802.11 protocol. IEEE 802.11 is a set of medium access control and physical layer (PHY) specification for implementing wireless local area network (WLAN) computer communication in the frequency bands.

Abstract - Wireless technology services have made instant and prodigious changes in the field of communication from the ultimate 20 years. Due to this swift expansion in free space and wireless technology, users can easily and with less effort access data from various locations. Wireless technology is preferred service in the world nowadays. The key of prosperous evaluation in wireless services is by reason of serial advance approaches. Periodically revolutions have changed state of life and intensions of such interminable promotions in cell and internet technology are to recoup the demerits of previous one. The focal points of this paper are to probe the various batches of mobile wireless technology and internet services from the very beginning to future (first G to Fifth G) and to explain the major remarkable issues that have been made from earlier to next generations and the expected exploration from the upcoming G (5G) of wireless technology.
