Maximizing data rate by adjusting codes and code rates |
摘要 |
The present invention provides for making code rate adjustments and modulation type adjustments in a pseudonoise (PN) encoded CDMA system. Coding rate adjustments may be made by changing the number of information bits per symbol, or Forward Error Code (FEC) coding rate. A forward error correction (FEC) block size is maintained at a constant amount. Therefore, as the number of information bits per symbol are increased, an integer multiple of bits per epoch is always maintained. The scheme permits for a greater flexibility and selection of effective data rates providing information bit rates ranging from, for example, approximately 50 kilobits per second to over 5 mega bits per second (Mbps) in one preferred embodiment. |

1. A subscriber unit comprising:
a forward error correction (FEC) decoder configured to FEC decode a plurality of data blocks, wherein each of the plurality of data blocks is a fixed size and encoded with an error correction code, and to strip redundant FEC code bits from the plurality of data blocks and generate a plurality of decoded segments based on the plurality of data blocks, wherein each of the decoded segments is a variable number of data bits; and a controller configured to select a decoding rate and to signal the selected decoding rate to the FEC decoder. |
