Abstract:

This report discusses four topics 1 Operation of a frequency acquisition aid to acquire a direct sequence or frequency hopped signal. The acquisition aid employed is a FFT, and repeated measurements are employed to reduce the probability of error 2 Multiple access using dynamic reservations. Here a new multiple access technique is described in which reservations are made which indicate whether the number of packets to be transmitted is to be increased or decreased. This technique is compared to the generally used procedure of indicating in the reservation the exact number of packets to be sent, a technique which requires significantly more bandwidth. Author
