The invention provides an apparatus and method for generating overspread orthogonal codes. Overspread orthogonal codes are generated code-multiplying orthogonal codes generated by any method and the overspread orthogonal code length is the product of the code lengths of the orthogonal codes that were...http://www.google.com.tw/patents/US6700864?utm_source=gb-gplus-share專利 US6700864 - System and method for generating orthogonal codes
