A method of receiving a frame includes receiving a first frame from a first access point associated with a terminal, comparing a signal level of the first frame with a preset data rate, performing a pre-procedure for interference alignment when the signal level of the first frame is less than the preset data rate, receiving a second frame from the first access point, and aligning interference of the second frame based on information obtained through the pre-procedure.

Wireless communication system for giga bit data rate and low power consumption
This invention is related to a wireless communication system for giga bit data rate and low power consumption, comprising a mobile communication terminal that transmits massive data to a display apparatus using a millimeter wave or terahertz wave band, a display apparatus that plays received massive data and a low speed wireless controller that controls the operation of the mobile communication terminal and the transmission of massive data from the mobile communication terminal into the display apparatus.. .
Ethernet point to point link incorporating forward error correction
A method of providing forward error correction on an ethernet point-to-point link, constituted of: receiving at one end of the point-to-point link an input data stream, wherein the input data stream is a 10 bit symbol encoded serial data stream at a first data rate; decoding the 10 bit encoded data stream to a 9 bit symbol data stream; increasing the data rate of the 9 bit symbol data stream to a second data rate; for each segment of a predetermined number of 9 bit symbols generating a respective plurality of parity symbols; combining the segments and the generated respective plurality of parity symbols into fec appended segments; encoding the fec appended segments into an output 10 bit symbol encoded data stream; and transmitting the output 10 bit encoded stream on the point-to-point link at the second data rate.. .
