dsss_chaotic
1. BPSK modulation of data which ever you input (default data is
“MANIPAL REDDY”).
2. MANIPAL REDDY is changed into ASCII Format and into two-bit
format for BPSK Modulation.
3. Chaos is used for spreading the binary bit sequence.
4. Uniformly distributed Noise is added to Spread signal.
5. After reception Chaotic Chip sequence is used to recover message .
6. Filter is used for removing spikes and noise.
7. Note the filter is used is just for showing a little realisitic picture.
8. Appropriate filter should be used.
9. The original data in binary and recovered data in binary format are
compared

OFDM
Channel estimation techniques for OFDM systems based on a pilot arrangement are investigated. Channel estimation based on a comb type pilot arrangement is studied through different algorithms for both estimating the channel at pilot frequencies and interpolating the channel. Channel estimation at pilot frequencies is based on LS and LMS methods while channel interpolation is done using linear interpolation, second order interpolation, low-pass interpolation, spline cubic interpolation, and time domain interpolation. Time-domain interpolation is obtained by passing to the time domain by means of IDFT (inverse discrete Fourier transform), zero padding and going back to the frequency domain by DFT (discrete Fourier transform). In addition, channel estimation based on a block type pilot arrangement is performed by sending pilots in every sub-channel and using this estimation for a
