    摘要: A system for and method of implementing mobile commerce in a satellite radio broadcasting system. A unique program identifier is associated with each program segment of a broadcast. When a listener hears a program segment of interest, the listener causes the associated program identifier to be captured and thereafter to be transferred to a central location or hub. The transferring operation can be accomplished manually, via a media link or via a wireless network. Upon receipt of the program identifier at the central hub, the program identifier is used to determine information about the listener, obtain additional information regarding the program segment associated with the program identifier for the listener and/or initiate an e-commerce transaction involving the listener and/or other parties including merchandisers and advertisers

    摘要: 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.

    摘要: A method and apparatus in a digital wireless communication system (100) controls an inter-cell hand-off. First and second fixed units (102) receive a common synchronization signal from a controller (104), and a first wireless link is established between the first fixed unit and a portable unit (120) on a first frequency. The first wireless link is synchronized to the common synchronization signal, and frame synchronization is obtained between the fixed unit (102) and the portable unit (120) during establishment of the first wireless link. Frame synchronization is maintained only by maintaining bit synchronization while transmitting user data on the first frequency. A second wireless link is established between the second fixed unit (102) and the portable unit (120) on the first frequency if the first frequency is usable therebetween. The second wireless link is synchronized to the common synchronization signal. The first wireless link is disconnected after the second wireless link is established, thereby seamlessly completing the inter-cell hand-off.
