Consider the following $ M $-ary digital communication system with $ \mathrm{M}=4 $. Assume that all symbol are equally probable and that each symbol is transmitted within time duration $ \mathrm{T}=1 \mathrm{~s} $ over an AW channel with double-sided power spectral density $ \mathrm{N}_{0} / 2 $. The expression of the transmit signal with T is shown below. \[ \begin{array}{ll} s_{1}(t)=3 \cos (2 \pi t), & s_{2}(t)=3 \cos (4 \pi t) \\ s_{3}(t)=3 \cos (8 \pi t), & s_{4}(t)=3 \cos (16 \pi t) \end{array} \] i) How many bit(s) is/are represented by one symbol? (2 marks) ii) At least how many basis function(s) is/are needed to represent all symbols? Give the expression(s) of it/them. (3 marks) iii) The pair-wise error probability between signals j and k is denoted by $ \mathrm{P}_{\mathrm{e}}(\mathrm{j}, \mathrm{k}) $. Find $ \mathrm{P}_{\mathrm{e}}(\mathrm{j}, \mathrm{k}) $. ( 5 marks) iv) Find the Union bound for the average symbol error rate. (5 marks)

2. Critical analysis Q4 Suppose a group of British investors finances the construction of a plant to manufacture bay boats in Albuquerque, New Mexico. The construction of the plant will \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ U.S. GDP. Suppose the plant generates $300,000 in corporate profits this year. These profits will \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ U.S. GDP for which of the following reasons? Profits are not a component of GDP. Only losses count against GDP. Foreign income earned within U.S. borders must be deducted from production. Profits earned in the domestic economy are counted as part of GDP under the resource cost-income approach.
