#### Eye Diagram / Equalization

- eye_eq.m - Produces eye diagrams/equalization filter plots.
- Documents from Equalizer help session

#### Programs by Atul Salvekar

- Baseband Equivalents:
- script1_1.mPerforms a complete bandpass analysis of a system given a transmission channel. resp.mat is the response of the channel for the frequencies freq.mat. script1_1.m makes uses the following functions:
- Show_2sided.m:This function returns the two sided frequency response given a real signal.
- Freq_RC.m:Constructs a bandpass filter.
- Anal_Eq.m:Finds the analytic equivalent of a signal/system.
- Chan_anal.m:Produces the analytic equivalent of the output given the input and a filter.
- Chan_bbout.m:Finds the baseband signal given the analytic signal.
- Time_Resp.m:Converts frequency response to time response.
- Chan_out.m:
- AWGN_PSD.m:
- Cioffi_constant.m:
- Noise_Filt.m:Gives the output PSD of a filtered noise process.
- EquivNoise.m:Generates the equivalent noise channel(up to a phase).

- An example on decoding regions: These programs have to do with the homework problem that you were given in week 1 (1.7). The first is a .ps file that talks about decision regions and independence. This may be useful. The rest is a sweet of programs that were used to generate a decision region that you had to calculate in the homework.: Dec_Reg.ps, decreg2.m, n02.m
- This gives an example on the Theorem on Irrelevance: irrelevance.pdf
