As I read through your question and some of your comments, I get the impression that this faculty member has already done some work on your paper, presumably believing that he would be a co-author.
If so, I think it would be wrong to submit a solo paper with his improvements incorporated into the work. If you want to be sole author, then you should do ALL the work, including the proofreading, etc. – or at least have let the professor know up front that he would only be listed under the acknowledgements, so he could make an informed decision about whether or not it would be worth his time and effort to make those improvements. Proofreading and correcting is not a trivial feat.
More importantly, though, your question reminds me of a similar situation I experienced during graduate school. During a computer graphics course, my lab partner and I did a lot of work on an algorithm, and we ended up getting a paper published. Our instructor was also listed as a third author.
My partner and I developed and tested the algorithm, and our instructor did little but give us the problem. Did I feel slighted? No, and in hindsight, I now better understand his vital role in our work. These problems don't just pop up like dandelions, or infiltrate our email like spam – they are usually the result of extensive study, along with collaborative research with industry. In other words, without us students, he wouldn't have had an answer, but, without our instructor, we would not have had a problem of any meaningful significance.
If I see an IEEE paper with two authors, instead of presuming that the work was split evenly between those two, I'd probably assume that one author's principle role was to identify the problem, while the other worked the solution. That's so common that it's almost a given – such symbiotic relationships are ubiquitous in academia.
In other words, I think you misunderstand the nature of coauthorship in research. Your instructor thought the work you did was good enough for the two of you to get something published together. You ought to be appreciative of his guidance, happily put his name alongside yours, and get off to a good start in the realm of academic research.
