In this project we work with time and frequency §compressed multicarrier modulation, also known as 2-§dimensional Mazo signaling. Instead of a square §pulse for the basic pulse, we use a root raised §cosine pulse with excess bandwidth 30%. A decoder §based on soft successive interference cancellation §was proposed for this coded modulation, with results §below that desired. In this project we try to §improve it, by using a second stage decoder in §cascade after the first decoder. We can not use our §decoder alone as it make use of the results of the §first decoder. §This new decoder splits the received signal into §several subsignals, each involving just a few §subchannels. Then it decodes the subsignals by §reduced sequence estimation realised by the M-§algorithm; it combines the different results §obtained in order to find an optimal solution. §The new decoder works very well for Eb/N0 = 10dB; it §obtains a bit error rate of 10 5 for compressions §around 50%. Our improvements are significant, up to §a factor of 50 in decreased bit error rate.
