Abstract
A baseband processor includes a modulating unit and a converting unit. The modulating unit generates an orthogonal frequency division multiplexing (OFDM) symbol by modulating a bit stream. The converting unit converts the OFDM symbol from a frequency domain into a time domain, and adjusts a frequency of the OFDM symbol according to a frequency hopping sequence to perform frequency hopping in a digital domain.
Claims20
A baseband processor comprising:
- a modulating unit configured to generate an orthogonal frequency division multiplexing (OFDM) symbol by modulating a bit stream;
- and
- a converting unit configured to convert the OFDM symbol from a frequency domain into a time domain, and to adjust a frequency of the OFDM symbol according to a frequency hopping sequence to perform frequency hopping in a digital domain.
A baseband processor comprising:
- a converting unit configured to receive an orthogonal frequency division multiplexing (OFDM) symbol, to convert the OFDM symbol from a time domain into a frequency domain, and to adjust a frequency of the OFDM symbol according to a frequency hopping sequence to perform frequency de-hopping in a digital domain;
- and
- a demodulating unit configured to generate a bit stream by demodulating the OFDM symbol provided from the converting unit.
