    • A method and apparatus detects (516) a baud rate in a digital signal (442). An N-state counter (404) counts at a rate N times the baud rate and the digital signal is sampled (504) to detect transitions of the digital signal. N tallies (202) record how many transitions occur coincident with each of the states of the counter, and a total number of transitions detected is computed (508). M groups (204-210) of the tallies are formed (510) corresponding to contiguous sequential states of the counter, and for each group a group number is calculated (512) indicating how many transitions are recorded in the tallies of the group. Each group is defined (514) transitional if the group number exceeds a percentage (413) of the total number of transitions, and the baud rate is determined present or absent based upon the groups that are defined as transitional.

    • A channel scanning communication receiver (204) operates in a system that transmits information in cycles (104) including subsequences (106). The receiver determines whether to operate in a scanning or locked mode by making (302) signal quality pass/fail decisions for subsequences transmitted in a predetermined group of cycles. A decision is made for a transmission of a subsequence, and subsequence active/inactive decisions are made (304) for the subsequences transmitted in the predetermined group of cycles, based upon the signal quality pass/fail decisions made for the subsequences. The receiver determines (306) whether the system is time-shared or continuous, based upon how many active decisions and inactive decisions are made, and selects (310, 312) the scanning or locked mode in accordance with predetermined rules for time-shared or continuous systems, according to whether the system is time-shared or continuous.

    • A novel and useful apparatus for and method of securely downloading and installing a patch program in a processing device. Each processing device is assigned a unique key embedded therein during manufacture and has knowledge of a shared key. The program patch is encrypted using the shared key and transmitted over a communication link, such as a satellite radio link, to each device. The patch is decrypted using the shared key and re-encrypted using the unique key known only to the device itself. The re-encrypted patch program is stored in nonvolatile memory and upon reset of the device, the encrypted patch contents are read out of the nonvolatile memory, decrypted using the unique key and loaded into patch memory for execution by the processing device.
