Consider a circular array of radius R normalized by the carrier wavelength with n elements uniformly spaced.
1. Compute the spatial signature in the direction cp.
2. Find the angle, f(cp1, cp2), between the two spatial signatures in the direction cp1 and cp2.
3. Does f(cp1, cp2) only depend on the difference cp1 - cp2? If not, explain why.
4. Plot f(cp1, 0) for R = 2 and different values of n, from n equal to f1rR/2l, f1rRl, f21rRl, to f41rRl. Observe the plot and describe your deductions.
5. Deduce the angular resolution.
6. Linear arrays of length L have a resolution of 1/L along the cos cp-domain, that is, they have non-uniform resolution along the cp-domain. Can you design a linear array with uniform resolution along the cp-domain?

Describe the distribution of the eigenvalues
: Consider a MIMO system with Lt = Lr = 2 in a channel with M = 10 multipaths. The ith multipath makes an angle of iLlcp with the transmit array and an angle of iLlcp with the receive array where Llcp = 1r/M. Assuming there are nt transmit and nr..

Is the proposed way of using dual transmit antennas smart
: Suppose there is only a single user (i.e., K = 1). From your plot in part (1), do you think the dual transmit antennas provide any gain? Justify your answer. Hint: Use Jensen's inequality.
