Interference channel capacity region for randomized fixed-composition codes - Chang, Cheng
Keyword(s): interference channels, randomized coding, capacity region
Abstract: The random coding error exponents are studied [5], [6] for the finite alphabet interference channel (IFC) with two transmitter receiver pairs. The code words are uniform on a fixed-composition set and the decoding is optimum, as opposed to decoding based on interference cancellation, and decoding th ...

XIntersectRegion(3X11) MIT X11R4 XIntersectRegion(3X11)
Name
XIntersectRegion, XUnionRegion, XUnionRectWithRegion, XSubtractRegion, XXorRegion, XOffsetRegion, XShrinkRegion - region arthmetic
Syntax
XIntersectRegion(sra, srb, dr_return)
Region sra, srb, dr_return;
XUnionRegion(sra, srb, dr_return)
Region sra, srb, dr_return;
XUnionRectWithRegion(rectangle, src_region, dest_region_return)
XRectangle *rectangle;
Region src_region;
Region dest_region_return;
XSubtractRegion(sra, srb, dr_return)
Region sra, srb, dr_return;
XXorRegion(sra, srb, dr_return)
Region sra, srb, dr_return;
XOffsetRegion(r, dx, dy)
Region r;
int dx, dy;
XShrinkRegion(r, dx, dy)
Region r;
int dx, dy;
Arguments
dest_region_return
Returns the destination region.
dr_return Returns the result of the computation. ds Dy move or shrink
dx
dy Specify the x and y coordinates, which define the amount you want to the specified region.
r Specifies the region.
rectangle Specifies the rectangle.
sra
srb Specify the two regions with which you want to perform the computation.
src_region
Specifies the source region to be used.
Description
The function computes the intersection of two regions.
The function computes the union of two regions.
The function updates the destination region from a union of the specified rectangle and the specified source region.
The function subtracts srb from sra and stores the results in dr_return.
The function calculates the difference between the union and intersection of two regions.
The function moves the specified region by a specified amount.
The function reduces the specified region by a specified amount. Positive values shrink the size of the region, and negative values expand
the region.
