Anyone know how to implement OFDMA transmitter block after modulation?
How can I put pilot subcarriers with data subcarriers to be a cluster?
Still confuse about the subcarrier allocation, please help me!
I am working on OFDMA 1024 FFT in DL PUSC.
The number of data subcarrier=720
I will...
In 802.16e OFDMA PHY, following two interleaving permutations should be implemented in Simulink model.
mk =(Ncbps ⁄ d)⋅ kmod(d) + floor(k ⁄ d)
jk =s floor (mk⁄ s)+(mk + Ncbps – floor(d ⋅ mk ⁄ Ncbps))mod(s)
where k = 0, 1, …, Ncbps – 1 and d = 16
In my case, I am running a DL PUSC in 1024...
For some OFDM based system like WLAN/WMAN, they require to scramble the signal first and then perform following functions. I am confused about how to implement the randomizer in simulink? Most of the cases I saw,they used bernoulli to achieve the requirement but how can I adjust the parameters...
Hello..
Recently,I am working on OFDMA PHY layer simulation in WirelessMAN 16e
I am gonna use simulink to simulate the signal Tx/Rx.
Data-->Mapping--->IFFT---->P/S transfer---->Tx
Dara<--Demap<----FFT-----<S/P transfer<----Rx
any idea how to implement that in Matlab simulink?
many thanks!
