6) (30 points) Consider the following transmitted waveform $$x(t)=A.cos(2\pi f_1t)-B sin(2\pi f_2t)$$ where A and B can take any value from the following set {-3, -1, 1, 3}. $$f_1$$ and $$f_2$$ are separated by 2 MHz. Assume that all symbols are equally likely and the symbol duration is 1 ms. Assume that input bits are independent and identically distributed with uniform PDF. What can you say about the modulation type, receiver structure, bit rate, possible basis functions, signal constellation, average energy per bit.
