Consider a simo system, in which the sender has one antenna and the receiver has 2 antennas. suppose the sender sends bpsk signals and the receiver has established perfect symbol timing and carrier frequency offset compensation based on the signal received from antenna 1. suppose the two samples from the two antennas are -0.5+0.1j and 0.2+3j, respectively, and channel coefficients are 1 and 2j, respectively (the channel coefficient is defines as the sample the receiver sees if the sender sends 1 in the absence of noise). which statement is true?

You have two photos of a person walking. one shows the person at the corner of third and main streets, the other shows the person at the corner of tenth and main streets. there are lampposts at every corner in this town, and the first picture shows it to be 10: 32: 00 exactly. the second picture shows it to be 10: 49: 30. you know three facts: (1) all of the clocks are synchronized; (2) there are exactly 12 equal-sized blocks per kilometer in this town; and (3) the streets that cross main in this area are numbered consecutively, with no interruptions. what is the person’s average speed in kilometers per hour?
