genetic algorithm papr reduction in ofdm matlab code

Abstract

Orthogonal Frequency Division Multiplexing (OFDM) is a form of multicarrier modulation Technique. In this System orthogonally placed subcarriers are used to carry the data from transmitter end to receiver end and has found its way to the high speed wireless and mobile communication world. It has excellent immunity against fading and ISI but its major drawback is peak to average power reduction (PAPR) of the transmitted signal. So many methods are proposed to reduce large PAPR. But ....etc

good morning sir,
i want to use aco algorithm for vanet broadcasting . basically i don't have much knowledge about aco algorithm . so i request you sir to give me some guidelines to use aco algorithm , particularly to avoid broadcast storm problem in vanet.
thanking you sir, ....etc

Abstract

The demand for high-speed mobile wireless communications is rapidly growing.
OFDM technology promises to be a key technique for achieving the high data capacity and spectral efficiency requirements for wireless communication systems of the near future. This work presents an investigation into methods for maximizing the spectral efficiency of Orthogonal Frequency Division Multiplexing (OFDM) systems. The current standards such as IEE 802.11a in USA and H ....etc

Abstract

Comparative studies on DWT-OFDM and FFTOFDM systems are presented. The model for DWT-OFDM includes zero-padding and vector transpose for transmitting the OFDM signal. MATLAB simulation commands are also described. The discrete wavelet transform-OFDM (DWT-OFDM) has to satisfy the orthonormal bases and the perfect reconstruction properties to be considered as wavelet transform. Different wavelet families have been used and compared with the conventional F ....etc

Dear Madam/Sir,

My project topic is Optimization Of AODV routing protocol in manet using Ant Colony Optimization.

I want to implement it in MATLAB. but donot get any clue, how can i compare Aodv's throughput or other characteristics of AODV with using ACO and without using ACO.

I am trying to implement AODV code first.. but it did not plot any graph.. can you suggest me how can i compare prevoius problem by plotting graph.

Thank you in anticipation.

Yours sincerely,
Bubun ....etc
