preamble detection in ofdm synchronization
Hi,
I am currently making a OFDM receiver in Altera DSP builder...using 10 short preambles and 2 LP...so here is my question
1. when we detect the start of the packet using the short preamble....how do we know as to whether its SP1 , sp2 ...or SPi.
2.because based on this, we have to start with the long preamble detection.
i know the algorithm for sp packet detection and lp symbol sync ...but dunno the timing relation between the end of packet detection and symbol sync
pls help me out....its urgent !
thanks in advance
