“…As a matter of fact, BPSK uses phase variation of the carrier signal according to the input data to differentiate the bits '0' and '1'. BPSK is a well known method for modulation which uses finite number of phase where each phase is allocated a special pattern of binary digits [8]. This sequence of bits forms the symbol that is depicted by the particular phase.…”

“…The ever increasing need for more frequency resources has compelled the researchers to look for a solution. But most of the higher level modulation techniques produce denser constellations which in turn makes the system complex and energy inefficient [8]. Extended Binary phase shift keying has thus been proposed as an energy efficient solution to the problem.…”

In a last few decades there has been tremendous growth and a drastic rise in wireless communication technologies. The major issue that the world is facing today with the advent of so many sophisticated wireless communication devices is efficient utilization of the spectrum. Spectrum efficiency comes together with a tradeoff factor of energy consumption. Thus, the need of the hour is an energy and bandwidth efficient technique. DS-CDMA is one of the competitive and most investigated technique in wireless communication which caters the large demand at the same time with limited bandwidth. Existing modulation techniques does not promise to provide better performance in case of higher noise. Therefore, one looks for a better BER stipulated modulation format to improve and enhance the performance of the system. This article revisits conventional Binary phase shift keying method and compares its performance in terms of BER with a special Extended Binary Phase Shift Keying (EBPSK) modulation format for a DS- CDMA system. EBPSK scheme is flexible and simple which is easily integrated in a network and assures improved and enhanced performance.

“…The binary phase shift keying, or BPSK, is known as the simplest form of digital phase modulation. The signal in this digital phase modulation is a sequence of ones and zeros, thus the term binary [5]. The carrier signal is directly phase modulated in this digital phase modulation.…”

Digital Communication follows one fundamental concept and it is the transfer of information from one point to another over an analog channel. In our modern society there is one method which is versatile and widely used in transferring digital data and this method is called Digital Phase Modulation. In Digital Phase Modulation it is possible to use discrete values in the carrier frequency or amplitude in order to represent their values in ones and zeros. Given this possibility, it can be concluded that it is also possible to represent digital data using phase. Such technique is called Phase Shift Keying. The easiest approach to Phase Shift Keying is the Binary Phase Shift keying or BPSK. In Binary Phase Shift Keying, hinted from the keyword binary, it uses only two phases with each used for logic high and logic low which can be represented with a minimum and maximum value of 0 degrees for logic low and 180 degrees for logic high. This Modulation Technique utilizes a balance modulator which consists of a carrier sine wave and a binary sequence which is to be used as input in order to generate the Phase Shift Keying Output desired.

“…In reality, fabricating MEMS beams of ideal anchors with the precise intended design dimensions is hard to achieve practically due to fabrication imperfections, such as undercuts near anchors and initial deformation of MEMS beams due to residual stresses. Small deviations from the ideal conditions indeed occur at the ends [ 24 , 25 ]. The concept of non-ideal boundary conditions has been proposed to be applied to micro/nano-resonator systems [ 11 , 26 ].…”

Normally, the boundaries are assumed to allow small deflections and moments for MEMS beams with flexible supports. The non-ideal boundary conditions have a significant effect on the qualitative dynamical behavior. In this paper, by employing the principle of energy equivalence, rigorous theoretical solutions of the tangential and rotational equivalent stiffness are derived based on the Boussinesq's and Cerruti's displacement equations. The non-dimensional differential partial equation of the motion, as well as coupled boundary conditions, are solved analytically using the method of multiple time scales. The closed-form solution provides a direct insight into the relationship between the boundary conditions and vibration characteristics of the dynamic system, in which resonance frequencies increase with the nonlinear mechanical spring effect but decrease with the effect of flexible supports. The obtained results of frequencies and mode shapes are compared with the cases of ideal boundary conditions, and the differences between them are contrasted on frequency response curves. The influences of the support material property on the equivalent stiffness and resonance frequency shift are also discussed. It is demonstrated that the proposed model with the flexible supports boundary conditions has significant effect on the rigorous quantitative dynamical analysis of the MEMS beams. Moreover, the proposed analytical solutions are in good agreement with those obtained from finite element analyses.
