Question

Consider the OFDM Transmitter by synthesising the 8 length composite signal using IDFT.. operation with sampling frequency of 16kHz. Consider a binary data (by mapping +5 indicating 1 bit: -5 indicating 0 bit respectively). Now, modulate the binary data (1,0) using real subcarriers of carrier frequencies 2 and 4 kHz respectively. (Hint: Use analysis and synthesis in the balanced form)

Step 1

In this case, +5 represents a 1 bit and -5 represents a 0 bit. So, the symbols corresponding to the binary data (1,0) would be (+5, -5). Show more…
