A channel of bandwidth 10 kHz with single-sided noise power spectral density 10 -7 W/Hz is available.

Question:

A channel of bandwidth 10 kHz with single-sided noise power spectral density 10^-7W/Hz is available. A data rate through it of at least 4 kbps is desired at a P_E ≤ 10^-6. Design at least two data transmission systems that will achieve this data rate but don’t require acquisition of a coherent reference at the receiver. That is, specify the modulation scheme meeting these requirements and find the required received-signal power. Simplicity is an important requisite.

I can also assists students with homework questions and test preparation strategies and I am able to help students in math, gre, business , and statistics I consider myself to have excellent interpersonal and assessment skills with strong teaching presentation verbal and written communication I love tutoring. I love doing it. I find it intrinsically satisfying to see the light come on in a student's eyes. My first math lesson that I taught was when I was 5. My neighbor, still in diapers, kept skipping 4 when counting from 1 to 10. I worked with him until he could get all 10 numbers in a row, and match them up with his fingers. My students drastically improve under my tutelage, generally seeing a two grade level improvement (F to C, C to A, for example), and all of them get a much clearer understanding! I am committed to helping my students get the top grades no matter the cost. I will take extra hours with you, repeat myself a thousand times if I have to and guide you to the best of my ability until you understand the concept that I'm teaching you.
