Abstract
An apparatus and a method are provided for generating and transmitting one or more band segmented bootstrap signals. For example, a transmitter may be configured to generate a plurality of sequence numbers and apply cyclic shift to each of the plurality of sequence number. The transmitter is further configured to map each of the shifted sequence numbers to at least one frequency domain subcarrier of a plurality of frequency domain subcarriers, and translate each subcarrier of the plurality of subcarriers to a time domain sequence. Each subcarrier of the plurality of subcarriers may be shifted with respect to other subcarriers of the plurality of subcarriers, thereby aligning each segment of the band segmented bootstrap signals next to each other in the frequency domain.
Claims20
A transmitter for generating band segmented bootstrap signals, comprising:
- a memory configured to store program instructions;
- and
- a processor, upon executing the program instructions, configured to:
- generate a plurality of sequence numbers;
- apply a cyclic shift to each of the plurality of sequence numbers;
- map each of the shifted sequence numbers to at least one frequency domain subcarrier of a plurality of frequency domain subcarriers;
- and
- translate each subcarrier of the plurality of subcarriers to a time domain sequence,
- wherein each subcarrier of the plurality of subcarriers is shifted with respect to other subcarriers of the plurality of subcarriers,
- thereby aligning, next to each other in a frequency domain, each segment of the band segmented bootstrap signals.
A method for generating band segmented bootstrap signals, comprising:
- generating a plurality of sequence numbers;
- applying a cyclic shift to each of the plurality of sequence numbers;
- mapping each of the shifted sequence numbers to at least one frequency domain subcarrier of a plurality of frequency domain subcarriers;
- and
- translating each subcarrier of the plurality of subcarriers to a time domain sequence,
- wherein each subcarrier of the plurality of subcarriers is shifted with respect to other subcarriers of the plurality of subcarriers,
- thereby aligning, next to each other in a frequency domain, each segment of the band segmented bootstrap signals.
A non-transitory, tangible computer-readable device having instructions stored thereon that, when executed by at least one processor, cause the at least one processor to perform operations comprising:
- generating a plurality of sequence numbers;
- applying a cyclic shift to each of the plurality of sequence numbers;
- mapping each of the shifted sequence numbers to at least one frequency domain subcarrier of a plurality of frequency domain subcarriers;
- and
- translating each subcarrier of the plurality of subcarriers to a time domain sequence,
- wherein each subcarrier of the plurality of subcarriers is shifted with respect to other subcarriers of the plurality of subcarriers,
- thereby aligning, next to each other in a frequency domain, each segment of band segmented bootstrap signals.
