METHOD AND SYSTEM FOR ADAPTIVE CONTROL OF SUB-CARRIERS |
摘要 |
A method and system for adaptive control of sub-carriers is useful for increasing frequency diversity gain to improve bit error rate performance in an Interleaved Frequency Division Multiple Access (IFDMA) system. The method includes selecting a combination of a Repetition Factor (RF) and a repetition block size (Q), from possible combinations of a RF and a Q, based on a number of users (Nu) (step 1405). A Spreading Factor (SF), Forward Error Correction (FEC) coding rate (R), or modulation order (M) based on the Nu is then determined (step 1410). Control signals are then provided based on the RF and Q, and based on the SF, R, or M (step 1415). |
