File Information

M-file for simulating a QPSK transmitter by modulating with a pseudo random bit stream. A serial to parallel conversion of the pseudo random bit stream is performed with mapping of two bits per symbol. A cosine and sine carrier is configured and the I and Q symbols modulate these carriers. The I and Q carriers are combined and time and frequency domain plots are provided showing key waveforms at various positions in the QPSK transmitter.

hola para todos udtedes,ablo el espa├▒ol pues ingles muy poco me gustaria formar parte de los forums que se dan en internet de temas de matlab que en mi carrera profesional lo utilizamos bastante, en estos momentos estoy haciendo un proyecto usando el matlab para una modulacion QPSK, transmitir datso entre maquinas de forma inalambrica usando una modulacion QPSK gracias por dejarme ser parte de ustedes
