实现pi/4DQPSK调制

function [I_TxWaveform, Q_TxWaveform] = TransmitFilter(I_Symbols,Q_Symbols,hTransmitFilter,numSamplesPerSymbol)
% The first step is to convert the symbol stream into a digital signal so that it can
% be filtered.
I_Waveform = SymbolToWaveform(I_Symbols,numSamplesPerSymbol);
Q_Waveform = SymbolToWaveform(Q_Symbols,numSamplesPerSymbol);
% The next step is to filter the signal to obtain the transmit waveforms.
I_TxWaveform = conv(I_Waveform,hTransmitFilter);
Q_TxWaveform = conv(Q_Waveform,hTransmitFilter);
