Hi
I'm developing a custom OFDM modem. I use 52 carriers each encoding one
nibble, so 26 bytes at a time.
In order to avoid large peaks on transmit, I Xor the 26 bytes with

Hi,
The correlation function is defined as:
Cxy(t) = intmipi[x(t + tau) y(tau) dtau], or alternatively,
Cxy(t) = intmipi[x(tau) y(t - tau) dtau]
where intmipi integral from minus infi...LTE 15MHz downsampling question [12 articles]
