In radio communications, multiple-input, multiple-output (MIMO) is a method for multiplying the capacity of a radio link using multiple transmissions and receiving antennas to exploit multipath propagation. Explain with a proper diagram how MIMO achieves better efficiency and utilization of channels.

In an FIR digital filter, each sample in the output signal is found by multiplying M samples from the input signal by M predetermined coefficients, and adding the products.

In an FIR digital filter, each sample in the output signal is found by multiplying M samples from the input signal by M predetermined coefficients, and adding the products. The characteristics of these filters (high-pass, low-pass, etc.) are determined by the coefficients used. For this problem, assume M = 5000, and that single precision floating point math is used. a. How many math operations (the number of multiplications plus the number of additions) need to be conducted to calculate each...

A geosynchronous communications satellite in stationary orbit is used to relay radio messages from one point to another around the earth’s curved surface. Apply Newton’s second law to the satellite to find its altitude in meters above the earth’s surface. RE = 6.38 × 106 m, mE = 5.97 × 1024 kg, and G = 6.674 × 10−11 Nm2/kg2.
