Abstract
The present invention provides communication methods, systems, and apparatuses. Methods are provided in which a second signal for transmission is obtained by halving values of an initial portion and a tail portion of a first signal, and adding zeros following the tail portion. Upon or after reception, a third signal is obtained from the received second signal and used in obtaining information. Obtaining each of an initial portion and a tail portion of the third signal includes adding together at least a portion of each of the initial portion and the tail portion of the second signal.
Claims6
A method for communicating information, the method comprising:
- obtaining a first signal;
- obtaining a second signal, comprising multiplying each of a value or values of an initial portion of the first signal by a number, and multiplying each of a value or values of a symbol tail portion of the first signal by a number, such that each corresponding pair of initial portion and symbol tail portion values are multiplied by a first number and a second number, respectively, and wherein, for each corresponding pair of initial portion and symbol tail portion values, a sum of the first number and the second number is equal to one;
- and
- upon or after reception of the second signal, obtaining a third signal from the received second signal, the third signal being used in obtaining information, wherein obtaining each of an initial portion and a tail portion of the third signal comprises adding together at least a portion of each of an initial portion and a symbol tail portion of the second signal.
A method for communicating information, the method comprising:
- obtaining a first signal;
- obtaining a second signal by halving values of an initial portion and a tail portion of the first signal, and adding zeros following the tail portion;
- and
- upon or after reception of the second signal, obtaining a third signal from the received second signal, the third signal being used in obtaining information, wherein obtaining each of an initial portion and a tail portion of the third signal comprises adding together at least a portion of each of an initial portion and a tail portion of the second signal.
A method for communicating information, the method comprising:
- obtaining a first signal that comprises an Inverse Fast Fourier Transform output signal;
- obtaining a second signal for transmission using OFDM, by halving values of an initial portion and a tail portion of the first signal, and adding zeros following the tail portion;
- upon or after reception of the second signal, obtaining a third signal from the received second signal, wherein obtaining each of an initial portion and a tail portion of the third signal comprises adding together at least a portion of each of an initial portion and a tail portion of the second signal;
- and
- processing at least a portion of the third signal to obtain information.
