I have written Matlab script for BPSK modulation. The way my code works is as follow:
series of 0 and 1----> nrz data (continuous rectangular pulses with amplitude -1 and 1)--->multiply by carrier----> add noise--> multiply by carrier---> integration--->detection---> Bit Error collection?
I would like to know can

i am having problem in plotting the demodulated signal, graph shows nothing, can anyone help....
and further , How to calculate BER?
Here is the code......
clear; % Clear all stored variables
Ns=100; %Number of data bits
nrz=2*data-1;% Converts 0 t

I am working on a senior design project to develop a laser key system.
Currently we are directly modulating our laser with the output of a PIC microcontroller (which is a code fragment that is hardcoded). We are outputting this in the nrz(L) standard for binary codes, but we want to modulate this digital signal with a (...)

Is anyone there can guide me or help to generate verilog code for the PRBS 2^31-1 pattern generator of nrz signal. Currently what I have is the PRBS that can generate signal up to 2^23-1 only. I'm not well exposed to the verilog coding, thus seeking the guide from the poeple in this forum.

Are you doing this in software or hardware?
Encoding a manchester signal is very easy. To encode a nrz signal to a manchester signal, you simply xor the nrz signal with a clock running 2 times the baud clock.
00 00 00 11 11 00 00 --->nrz data
01 01 01 01 01 01 01 --->2x Baud clock
01 01 01 10 10 01 (...)

I'm designing a UHF passive RFID tag (Type-B of ISO-18000-6). The date link coding from reader to tag is 40K bps Manchester nrz. The frame contains nine 0-1s preamble preceding the delimitter field and data field. I measure the time durations of high and low signal levels using a LO to estimate the data clock period, then decode the sign

Hello, I want to use nrz(non return to zero) for input,
then convert to Manchester code, how can i write this program ???
any reference ? thanks !
