	For a coarse quantization with 2 bits, three to four iterations generally suffices to achieve a good Bit-Error Rate. It is observed that an additional iteration is generally needed in fixed-point implementation over the floating-point implementation to match their Bit-Error Rates. It is also apparent that for a quantization with 2 bits, the worldength of Q has little impact on the Bit-Error Rate: 0.0823 is achieved for qwl=6, and 0.0794 is achieved for qwl=7. On the other hand, the wordlength of Theta has a much stronger impact on the Bit-Error Rate: 0.0823 is achieved for theta wl=9, and 0.0395 is achieved for theta wl=10.
