Number of qam symbols per frame
Web25 aug. 2008 · The four symbols represent the binary numbers 00, 01, 10, and 11. Therefore, if a symbol rate of 2.56 Msymbols/s is used to transport a QPSK carrier, then it would be referred to as 2.56 Mbaud and the theoretical bit rate would be 2.56 Msymbols/s × 2 bits/symbol = 5.12 Mbps. This is further explained later in this document. Web7 jun. 2016 · The problem I am running into is what the "Number of OFDM Symbols" is. Do I need to convert the QAM serial signal into Parallel data streams first? Say my sample per frame is 20, I could then parallel this into 10x2 which is an FFT size of 10 (assuming no guard bands or DC null), and 2 symbols?
