    摘要: Methods and systems are provided for determining a transmission format using an effective SNR. The method comprises determining (105) a pilot SNR for at least one time period in a frame, mapping (110, 115, 120, and 125) the scaled SNRs of the frame to a second SNR for at least one transmission format, and selecting (130) the transmission format based on the second SNRs. The system comprises a receiver (24) configured to detect pilot signals, a data storage (36), and a processor (26) coupled to the receiver and data storage. The data storage (36) comprises tables of capacity mapping functions and Q factors for each transmission format The processor (26) comprises a set of instructions to convert SNRs of different pilot signals to a second SNR using the tables and Q factors and select the transmission format based on the second SNR.
