Apparatus and method for selecting modulation and filter roll-off to meet power and bandwidth requirements |
摘要 |
A base station for use in a wireless network that communicates according to a multi-carrier protocol. The base station receives an uplink signal transmitted by a subscriber station. The subscriber station transmits using a configurable spectral shaping filter and a selectable modulation order. The base station determines a required bandwidth efficiency associated with the subscriber station and, in response to the determination, selects a modulation order and a filter parameter to be used by the subscriber station. Advantageously, the base station selects the modulation order and the filter parameter in order to maximize a power efficiency of the subscriber station while maintaining the required bandwidth efficiency. |
