This figure shows the procedure for CQI selection.CQI Selection Without SINR Lookup Table The function computes the CQI values by using the SINR values across all layers corresponding to the reported PMI. Based on the number of codewords, the function forms the combinations of CQI values and ...
Error evaluating 'InitFcn' callback of block_diagram 'MIMO_OFDM_VBLAST'. Undefined function or variable 'MIMO_parameter'. i tried to do right click on an empty spot in the model and select Model Properties; and tried to go to the Callbacks tab . Bu...
At the output of this function, the generated waveform has a sampling rate equal to the channel bandwidth. For all EHT, HE, VHT, HT, and non-HT format OFDM modulation, the channel bandwidth is configured via the ChannelBandwidth property of the format configuration object. For the DMG format...
BPSK and QBPSK Demapping for VHT-SIG-A Field Copy Code Copy Command BPSK and QBPSK demapping for different OFDM symbols for the VHT-SIG-A field by using a soft demodulation. The demapping is defined in IEEE® 802.11ac™-2013 Section 22.3.8.3.3 Create the sequence of data bits. Spec...
% If the function finds the specified PSS, the receiver OFDM demodulates the SSB % resource grid and attempts to detect its SSS. In demodulation % mode, the function returns these results. % % * Updated parameters for only the specified SSB if the PSS...
[ofdmResponse,timingOffset] = tdl(carrier) returns only the OFDM channel response and timing offset without filtering an input signal. The tdl object and the carrier input act as a source for the calculation of the OFDM channel response and timing offset. To use this syntax, you must also ...
