Algorithm | Number of complex correlators | Notes |
---|---|---|
BJ | 5-- bipolar/binary | The local code is a bipolar sequence and code multiplication can be effectively implemented using sign changes Additional logic/circuitry is required for the generation of the local subcarrier replica. The number of multiplications is double since local code and sub-carrier are wiped-off separately |
DE | 5-- bipolar/binary | |
MMSES (time domain implementation and independent phase tracking) | 3--real 1--bipolar/binary (for independent phase tracking) | The filtered local code is stored in memory and multi-bit multiplications are required for the code wipe-off |
