Question about the way Smith defines frames of an input signalfor the STFT

In the first equation on this page: http://ccrma.stanford.edu/~jos/parshl/Short_Time_Fourier_Transform_STFT.html The mth frame of the input signal is defined as: x(n-mR), where R is the hop size and n is the sequence of input signal sample index numbers of the first frame (m=0). This makes sense to me, except fo... 14 Jul 2008 15:45

Convolution relation
I have a question about a particular relationship with convolutions. We want to transmit a particular waveform X, but through that process the input signal X gets convolved with some annoyance term H and we actually send Y. I.e. Y = H * X (where * = convolution) By knowing the X we want and the Y we actually e... 12 Jul 2008 15:37

Spreading and Scrambling in UMTS (WCDMA) --> DESPREADING
I am attempting to simulate a WCDMA system from the 3GPP standards and I am aware that the OVSF channelisation codes provide the spreading operation and the scrambling codes (terminal specific) are applied on a chip by chip basis multiplication to the sum of the channelised data. That is, simply for demonstratio... 11 Jul 2008 16:07
