To alleviate the requirement to back-off all up-link performance, such as by limiting power spectral density, to overcome far-end cross-talk problems otherwise associated with relatively short loop-length wireline links, the present invention partitions the frequency spectrum based on an estimate of the loop length of a subscriber unit (CPE) modem from an exchange (LTE) modem. Up to a threshold frequency (fmax) at which received transmissions from a subscriber having a longest loop length (115) become indistinguishable by the LTE modem from a noise floor (102), up-link performance on all loop lengths is limited to correspond to that of the longest loop. At frequencies above the threshold frequency (fmax), subsets of subscribers (152-154) having relatively short loop lengths (116-119) use high frequency carriers that have signal to noise ratios sufficient to support information transmission in these elevated frequency bands.

A suspensory graft ligament fixation device is shown to be particularly suitable for maximizing the contact between a soft tissue graft and the bone tunnel prepared to receive the graft. The suspensory fixation device has an elongated anchor member adapted to be transversely situated at the exit of the bone tunnel.

When a graft ligament is attached to the saddle end of the loop, the length of the loop member may be shortened to pull the graft member into the bone tunnel until it bottoms out at the floor of the bone tunnel.

A method for LDPC check matrix configuration based on circular shift matrix grading extension, which comprises configuring a master matrix exclusive of loops with the length of 4, then searching the distribution of loop 6, 8 and 10 in the master matrix, adopting grading expansion method to fill the displacement parameters of the circular shift matrix in the position of 1 element in the master matrix, and finally using circular shift matrix and all 0 matrix to fill the master matrix expansion according to the positions of displacement parameter matrix and 0 element so as to generate check matrix. For timely and effective discovery of good codes with secondarily maximized minimum loop length and average minimum loop length, the invention only requires graded optimization of the combination of the master matrix with very small code length and the circular shift matrix; compared with the method of random circular shift configuration check matrix followed by comparing average minimum loop length, the search volume is significantly reduced. The check matrix not only has excellent performance, but also further reduces average iteration times. The invention is suitable for all methods that adopt circular shift matrix to constitute check matrix.

A knitted convolute protective sleeve is disclosed. The sleeve is knitted from filamentary members to form alternating crests and troughs lengthwise along the sleeve. The crests and troughs may be formed by alternatingly knitting segments from relatively stiff and relatively flexible filamentary members, by interlacing stiffening hoops at spaced intervals lengthwise along a knitted sleeve having a smaller nominal diameter than the hoops, or by varying the knitting parameters, such as loop density and loop length as a function of length along the sleeve.

A suspensory fixation device has an elongated anchor member adapted to be transversely situated at the exit of a bone tunnel. A graft supporting loop member formed of a pair of parallel suture limbs extending from a bight portion is suspended transversely from the anchor member and has a loop length which is adjustable so the graft ligament can be supported in the bone tunnel at varying distances from the anchor member. When a graft ligament is attached to the saddle end of the loop member, the length of the loop member may be shortened by simply pulling distally on the pair of limbs at one end of the loop member to pull the graft ligament into the bone tunnel a predetermined distance or until it bottoms out at the floor of the bone tunnel. When tension is applied to the loop member by the graft pulling the loop proximally, the bight portion of the suture automatically locks the graft supporting loop member in place.
