LTE OFDM detector cross correlation

Hi; Can you explain to me about coefficient Discrete FIR filter used in the detector side of the example (HDL Implementation of LTE OFDM Modulator and Detector) as shown in the link http://uk.mathworks.com/help/hdlcoder/examples/hdl-implementation-of-lte-ofdm-modulator-and-detector.html

Regards.

Hi Sameer,

Are you referring to the Discrete FIR Filter blocks used in the PSS cross-correlators?

Each PSS Xcorr subsystem implements a complex-input complex-coefficient FIR filter. The coefficients are matched to the time domain PSS sequences. The complex filters are decomposed into three real-input real-coefficient FIR filters.
