application example 1
[0234] The receiving end completes the interference noise estimation and data detection of each data stream through the following steps:
[0235] (1) The receiving end takes the received signal y on the ith pilot subcarrier of the current data stream in the interference suppression area p (i) Multiply with the conjugate of the pilot signal p(i) sent by the sending end on the i-th pilot subcarrier to obtain the estimated channel coefficient of the pilot subcarrier position which is:
[0236] h ^ p ( i ) = y p ( i ) p * ( i )
[0237] For the definition of each parameter, see above;
[0238] (2) Carry out channel coefficient estimation:
[0239] The receiving end divides the interferenc...
application example 2
[0260] In this example, one data stream is carried in the interference suppression area, and a 16e uplink pilot structure is adopted, such as figure 2 shown.
[0261] The receiving end completes the interference noise estimation and data detection corresponding to the data stream through the following steps:
[0262] (1) The receiver receives the received signal y on the i-th pilot subcarrier corresponding to the data stream p (i) Multiply with the conjugate of the pilot signal p(i) sent by the sending end on the i-th pilot subcarrier to obtain the estimated channel coefficient of the pilot subcarrier position which is:
[0263] h ^ p ( i ) = y p ( i ) p * ( i )
[0264] For the defi...
application example 3
[0287] In this example, two data streams are carried in the interference suppression area, and a 16e uplink pilot structure is adopted, as in image 3 shown.
[0288] For each data stream, the receiving end completes the interference noise estimation and data detection corresponding to the data stream through the following steps:
[0289] (1) The receiving end takes the received signal y on the i-th pilot subcarrier of the data stream p (i) Multiply with the conjugate of the pilot signal p(i) sent by the sending end on the i-th pilot subcarrier to obtain the estimated channel coefficient of the pilot subcarrier position which is:
[0290] h ^ p ( i ) = y p ( i ) p * ( i )
