Webgenerate_cpmsg_prach() in xran_common.c. The xran_cp_create_and_send_section() is to generate the C-Plane message with section type 1 for DL or UL symbol data scheduling. This function has hardcoded values for some parameters such as: The filter index is fixed to XRAN_FILTERINDEX_STANDARD. RB indicator is fixed to XRAN_RBIND_EVERY. WebA frequency domain filter, such as implementing inverse discrete Fourier transform (IDFT) with down-sampling using indices for PRACH recovery, may be utilized to extract PRACH …

WebDec 5, 2024 · In effect, the Alium pool license covers lower physical layer functionality including precoding, resource element mapping, beamforming, PRACH filtering and PRACH preamble responses, fast fourier transforms and their inverse, cyclic prefix insertion and extraction, digital to analog conversions, analog to digital conversions, and signal filtering. WebThe CIC and FIR filters convert in-phase and quadrature signals sample rate to 11.484 MHz while maintaining the input signals spectrum information. The decimation filters also reject out-of-band noise. Therefore, the output of this rate conversion system should be noiseless down sampled sinusoidal waves of frequency 4.57 MHz.
