Abstract
Keksinnön kohteena on häiriönpoistomenetelmä sekä vastaanotin, joka käsittää häiriönpoistovälineet (400) kapeakaistaisen häiriösignaalin poistamiseksi vastaanotetusta signaalista, välineet (400) suorittaa signaalille ortonormaali muunnos haluttuun aliavaruuteen aliavaruuskomponenteiksi, muunnosvälineiden (400) ulostuloon toiminnallisesti kytketyn dekooderin (402), jossa saadaan estimaatti vastaanotetulle signaalille. Dekooderin ulostulo on toiminnallisesti kytketty muunnosvälineille, ja muunnosvälineet on sovitettu määrittämään kapeakaistaisen häiriön ominaisuuksille estimaatti, jossa määrityksessä vähennetään vastaanotetusta signaalista dekooderin ulostulosta saatava estimaatti ennen ortonormaalin muunnoksen suoritusta. Häiriönpoistovälineet (400) on sovitettu vähentämään määritetyn estimaatin avulla vastaanotetusta signaalista niiden aliavaruuskomponenttien vaikutusta, jotka käsittävät kapeakaistaista häiriösignaalia.&sr;(Kuvio 4)
