Fortran has always been the principal language used in the fields of scientific, numerical, and engineering programming, and a series of revisions to the standard defining successive versions of the language has progressively enhanced its power and kept it competitive with several generations of rivals. Beginning in 1978, the technical committee responsible for the development of Fortran standards, X3J3 (now called J3), laboured to produce a new, much- needed modern version of the language, Fortran 90. Its purpose is to "promote portability, reliability, maintainability, and efficient execution... on a variety of computing systems". The standard was published in 1991, and work began in 1993 on a minor revision, known informally as Fortran 95. Now this Revised

The continuing vitality of spread-spectrum communication systems and the devel- opment of new mathematical methods for their analysis provided the motivation to undertake this new edition of the book. This edition is intended to enable readers to understand the current state-of-the-art in this field. Almost twenty percent of the materialinthiseditionisnew, includingseveralnewsections, anewchapteronadap- tive arrays and filters, and a new chapter on code-division multiple-access networks. The remainder of the material has been thoroughly Revised, and I have removed a considerable amount of material that has been superseded by more definitive results.

The first edition of this book was published in 1992. Nine years later it had become clear that a second edition was required because of the rapidly changing nature of telecommunication. In 1992, the Internet was in existence but it was not the household word that it is in the year 2001. Cellular telephones were also in use but they had not yet achieved the popularity that they enjoy today. In the current edition, Chapter 1 has been Revised to include a section on the Internet. Chapter 10 is new and it covers the facsimile machine; I had overlooked this important tele- communication device in the first edition. Chapter 11 is also new and it describes the pager, the cordless telephone and the cellular telephone system. These are examples of a growing trend in telecommunications to go ‘‘wireless’’.
