of decreasing the proliferation of cellular masts in many countries around the world, this collocation situation could occur quite frequently in practical networks and this will serve to decrease the impact of adjacent channel interference in areas where site sharing is used. However, site collocation is by no means a universal feature of cellular networks and we must also consider other ways of mitigating adjacent channel interference in practical networks. One approach that could be used in specific areas where adjacent channel interference is a significant problem is to increase the power of the wanted signals in the vicinity of an adjacent channel Node B using an on-frequency, off-air repeater, as shown in Figure 12.6. This approach has a similar effect to Node B collocation in that the wanted and adjacent channel signals increase and decrease together and the difference between the two signals remains relatively constant. This approach is complicated by the fact that, in order to solve interference problems in one network, it requires the cooperation of another, competitive network operator, i.e. the competitor must agree to having a repeater installed at its Node B site. The two mitigation techniques considered above rely on equalising the received power of the wanted and interfering signals. Another approach is to improve the suppression of adjacent channel interference by adding additional filtering at the Node B transmitter and receiver. Adding additional filtering at the Node B transmitter will improve the adjacent channel leakage ratio (ACLR) and this will decrease

must also be valid code words. But they are not. Another valid codeword is usually c 0 0 0 0 0 0 0 . The data value 0 0 1 1 , for example, yields the codeword 0 0 1 1 0 0 1 ; and not the allowed cyclic code 0 0 1 1 1 1 0 . The codeword c 0 0 0 1 0 0 0 could also not be a valid (7, 3) cyclic codeword. Why Because if it were, then c 0 0 0 0 1 0 0 would also have to be a valid codeword. This is not possible, for a parity value of `1' is not possible for non-zero user data (the rst four bits of the codeword). Not all block codes are cyclic codes!!

Some countries, including the United States and United Kingdom, make it very easy to download the paperwork and forms from their registration body via the Internet so you can set up your firm by yourself. If you are having a problem drafting suitable articles of association, go down to the offices of your state or country s business governing body and consult some of your rivals information (remember, these are publicly available). The registration body is not there to give you legal or corporate advice but to make sure you have the right forms and to answer questions in that regard. Whichever way you decide to go about setting up your firm, you will need to choose and agree on the following: Directors Corporate administrator/company secretary Registered office Memoranda and articles of association Details required on the forms include full names, addresses, dates of birth, occupations, and details of other directorships held within the last five years. They also require those companies registered offices. Although some of these details are held
