Receiver window shaping in OFDM to mitigate narrowband interference

A receiver module, comprising:

• a serial to parallel converter configured to receive a wideband signal carrying a symbol spread across a plurality of sub-carriers of a frequency band;
• and
• a window shaping module configured to obtain a first receiver window for extracting the symbol, wherein the window shaping module is configured so that the first receiver window has:
• a starting point before the start of the symbol;
• a first decaying edge between the starting point and the start of the symbol;
• and
• a second decaying edge in a zero padded portion of the symbol.

A receiver module, comprising:

• means for receiving a wideband signal carrying a symbol spread across a plurality of sub-carriers of a frequency band;
• means for obtaining a first receiver window for extracting the symbol, such that the first receiver window has:
• a starting point before the start of the symbol;
• a first decaying edge between the starting point and the start of the symbol;
• and
• a second decaying edge in a zero padded portion of the symbol.

A circuit for improving capture of a wideband signal, wherein the circuit is adapted to:

• receive a wideband signal carrying a symbol spread across a plurality of sub-carriers of a frequency band;
• and
• obtain a first receiver window for extracting the symbol, wherein the first receiver window has a starting point before the start of the symbol, and includes:
• a first decaying edge between the starting point and the start of the symbol;
• and
• a second decaying edge in a zero padded portion of the symbol.

A non-transitory computer-readable medium having stored thereon processor-executable instructions for receiver window shaping for symbol extraction, which when executed by a processor causes the processor to:

• receive a wideband signal carrying a symbol spread across a plurality of sub-carriers of a frequency band;
• and
• obtain a first receiver window for extracting the symbol, wherein the first receiver window has a starting point before the start of the symbol, and includes:
• a first decaying edge between the starting point and the start of the symbol;
• and
• a second decaying edge in a zero padded portion of the symbol.
