Abstract:

The aim of this project is studying MC CDMA system and use MATLAB to simulate the system and find the signal graphs at each part of the system , how the signal changes after coding and modulation , how the noise effect it at the channel , and how can we receive it by making decoding and demodulation. Also Study the performance of the MC-CDMA system in term of bit error rate with signal to noise ratio (SNR VS BER) for 2 kinds of modulation (BPSK, QPSK) and 2 kinds of channel (AWGN, Fading +AWGN). And make a comparison between all these cases and figure illustrate the cases we use in programming by studying various papers, books, notes as well as internet. Performance degradations due to above system impairments will be evaluated and optimum system design parameters will be determined. To minimize the error, this paper provides a solution which is solved through MATLAB.

Description:

Wireless communication is the transfer of information over a distance without the use of electrical conductors or "wires". The distances involved may be short (a few meters as in television remote control) or long (thousands or millions of kilometers for radio communications).At the point when the setting is clear, the term is frequently abbreviated to "remote". Remote correspondence is commonly viewed as a part of broadcast communications. It envelops different kinds of fixed, versatile, and compact two-way radios, cell phones, individual computerized associates (PDAs), and remote systems administration. Different instances of incorporate GPS units, carport entryway openers as well as carport entryways, remote PC mice, consoles and headsets, TV and cordless phones. Remote tasks grants administrations, for example, long range interchanges, that are outlandish or unreasonable to actualize with the utilization of wires. The term is normally utilized in the broadcast communications industry to allude to media communications networks (for example radio transmitters and recipients, remote controls, PC systems, arrange terminals, and so on) which utilize some type of vitality (radio recurrence (RF), infrared light, laser light, obvious light, acoustic vitality, and so forth) to move data without the utilization of wires. Data is moved as such over both short and long separations. Radio transmission through the air. Remote is an exceptionally conventional term that alludes to various types of transmission that don't utilize metal wires or optical strands. They incorporate AM and FM radio, TV, mobile phones, compact telephones and remote LANs. Different systems are utilized to give remote transmission, including infrared viewable pathway, cell, microwave, satellite, parcel radio and spread range. See arrange, cell, remote glossary, remote LAN, CMRS, PCS, FDMA, TDMA, CDMA and CDPD.
