{"Image DocumentName": "Multiple vs. Random Access", "Image ImageDescription": "Multiple Access Techniques. Used to create a dedicated channel for each user. Orthogonal (TD/FD with no interference) or semi-orthogonal (CD with interference reduced by the code spreading gain) techniques may be used. Random Access. Assumes dedicated channels wasteful - no dedicated channel assigned to each user. Users contend for channel when they have data to send. Very efficient when users rarely active; very inefficient when users have continuous data to send. Scheduling and hybrid scheduling used to combine benefits of multiple and random access.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
