Effect of Using Different Encoders in Bluetooth

چکیده
IEEE 802.11 and Bluetooth are the two different wireless systems that share the same frequency band in 2.4 GHz and are likely to interfere with each other if operating in the same environment and thus experience a severe decrease in throughput. The devices equipped with IEEE 802.11 and Bluetooth are mobiles, laptops, watches and many more and in future with WiMAX. Result is the number of co-located devices may cause interference issues in the 2.4 GHz radio frequency spectrum. Like other communication devices Bluetooth also consists of transmitter, channel and receiver. In transmitter and receiver encoders and decoders are used. In Bluetooth transmitter different types of encoders are used like RS encoder, Hamming encoder, CVSD encoder etc. these encoders have its own advantages and disadvantages. In this paper, by using of two different encoders like hamming encoder and CVSD encoder we analyse the communication of Bluetooth device and compare the

The Impact of Cooperative Learning and Mobile Learning through Bluetooth Device on Vocabulary Learning of Iranian EFL Learners
Cooperative learning has been found to affect different aspects of language learning by many researchers (e.g., Kagan, 1995; Kagan, 1999; Kessler, 1992; McGroarty, 1993). Likewise, mobile assisted language learning (MALL) has revealed significant impacts on the improvement of different language skills and components (e.g., Comas-Quinn et al. 2009; Divitini & Chabert, 2009; Motallebzadeh & Ganja...
متن کاملRobust Distributed Source Coding with Arbitrary Number of Encoders and Practical Code Design Technique
The robustness property can be added to DSC system at the expense of reducing performance, i.e., increasing the sum-rate. The aim of designing robust DSC schemes is to trade off between system robustness and compression efficiency. In this paper, after deriving an inner bound on the rate–distortion region for the quadratic Gaussian MDC based RDSC system with two encoders, the structure of...
متن کاملHigh-Speed and Low-Power Flash ADCs Encoder
This paper presents a high-speed, low-power and low area encoder for implementation of flash ADCs. Key technique for design of this encoder is performed by convert the conventional 1-of-N thermometer code to 2-of-M codes (M = ¾ N). The proposed encoder is composed from two-stage; in the first stage, thermometer code are converted to 2-of-M codes by used 2-input AND and 4-i...
متن کاملOptimum QAM - TCM Schemes Using Left - Circulate Function over GF ( 2 N )
In this paper, quadrature amplitude modulation – trellis coded modulation (QAM-TCM) schemes are designed using recursive convolutional (RC) encoders over Galois field GF(2 N ). These encoders are designed using the nonlinear leftcirculate (LCIRC) function. The LCIRC function performs a bit left circulation over the representation word. Different encoding rates are obtained for these encoders wh...
متن کاملOn the Impact of Fading and Inter-piconet Interference on Bluetooth Performance
In this paper we propose a simple method to evaluate the impact of fading and inter-piconet interference on Bluetooth performance. We consider in detail the joint effect, on packet error statistics, of interference produced by adjacent Bluetooth piconets and fading. Hence, we illustrate the proposed method by investigating the potential performance tradeoff among the different radio packet form...
