QPSK modulation with carrier and timing recovery loops

QPSK modulation with 50% SRRC pulses, NDA TED and DD PED recovery loops

Description

QPSK modulation with square-root raised cosine pulses of 50% rolloff factor. The timing recovery loops uses an interpolator with Farrow structure with an NDA timing error detector (approximate derivative). The phase recovery loop uses a DD phase error detector. Modified to be run with Matlab 2011b or higher (changed the QPSK modulator and demodulator and value of alpha to 0.5)

• Required Products: Simulink; MATLAB
• MATLAB release: MATLAB 7.13 (R2011b)

Sir,the model will be better understandable if reference is mentioned. Pl provide the same.
