Apparatus for detecting a transmitted symbol encoded with a time-frequency code (TFC) base sequence, the TFC base sequence generated from an intermediate binary hierarchical sequence based on predetermined binary sequences of the TFC, the apparatus comprising:
- a matched filter having predetermined coefficients based on a simplified version of the TFC base sequence.
A method for packet detection comprising:
- receiving a transmitted symbol encoded with a time-frequency code (TFC) base sequence in a transmitted signal, the TFC base sequence generated from an intermediate binary hierarchical sequence based on predetermined binary sequences of the TFC;
- and,
- filtering the received signal using a matched filter including a plurality of predetermined coefficients based on a simplified version of the TFC base sequence.
An apparatus for packet detection comprising:
- means for receiving a transmitted symbol encoded with a time-frequency code (TFC) base sequence in a transmitted signal, the TFC base sequence generated from an intermediate binary hierarchical sequence based on predetermined binary sequences of the TFC;
- and,
- means for filtering the received signal using a matched filter including a plurality of predetermined coefficients based on a simplified version of the TFC base sequence.
A computer program product, comprising:
- non-transitory computer-readable medium comprising:
- code for causing a computer to receive a transmitted symbol encoded with a time-frequency code (TFC) base sequence in a transmitted signal, the TFC base sequence generated from an intermediate binary hierarchical sequence based on predetermined binary sequences of the TFC;
- and,
- code for causing the computer to filter the received signal using a matched filter including a plurality of predetermined coefficients based on a simplified version of the TFC base sequence.
A processor, comprising:
