Leonard, M. Leonard, C. Richart, R. M. Pyle, and K. Novoselić. Diagnosis: See under preceding species. Etymology: The species name honors Robert Michael Pyle, a notable lepidopterist, author, conservation advocate, and as is this species, denizen of the Willapa Hills. Description: Male: Length, 5.0 mm. Fourteen ocelli in oval-triangular group. Metazonital shoulders poorly developed; segmental setae curved, acute. Legpairs one, two reduced, pairs three, four encrassate, pairs five to seven near same size as postgonopodal legs; femora three, four with basal femoral knobs acute, posteriorly directed.Anterior gonopods (ag, Figs. 244, 245) with large anterior sternum, widely separated, curving lateral to posterior gonopod coxites, apically decurved but without any apical expansion, small lateral branch tightly appressed to gonopod (free in Fig. 245 due to compression on microscope slide). Posterior gonopod telopodites reduced but relatively larger than in L. evergreen; posterior gonopod coxites (pgc, Figs. 244, 245) short, broad, anteriorly cupped, with broad, lamellate process mesally, basal pseudoflagellum originating posteriorly, two processes distolaterally, more lateral process composed of filaments (seen as separate in Fig. 246 due to compression on microscope slide), mesal process curved, apically fimbriate. Coxae 10, prefemora 11 as usual. Female 5.2 mm long, nonsexual characters as in male.

Loomisiella evergreen Shear & Richart & Wong 2020, new species
No full textLoomisiella evergreen, new species Figs. 240–243, 247–250 Types: Male holotype and male and female paratypes from WASHINGTON: Thurston Co., The Evergreen State College, Olympia, beside main parking lot, 47.0791°N, 122.9776°W, elev. 60 m, collected 14 February 2003, by W. Leonard, C. Richart. Diagnosis: Distinct from L. pylei, n. sp. in the more broadly flared tips of the anterior gonopods and in lacking a mesal plate-like process of the posterior gonopod coxites. The posterior gonopod telopodites of L. pylei are reduced, as in this species, but comparatively larger. Etymology: The species epithet, a noun in apposition, is from the type locality on the campus of The Evergreen State College, Olympia, Washington. Description: Male paratype: Length, 4.8 mm. Thirteen ocelli in oval to triangular group. Metazonital shoulders poorly developed, segmental setae curved, acute. Legpairs one and two reduced, pairs three to five encrassate, pairs six and seven about as postgonopodal legs; femora three and four with acute basal knobs. Anterior gonopods (ag, Figs. 240, 242, 243, 247, 248) widely separated at base, embracing posterior gonopod coxites, narrowed, with right-angled or less bend basal to flaring tip; small processes mesal at base. Posterior gonopod telopodites strongly reduced, femur about one-third length of prefemur, sternum broad, well-sclerotized anteriorly. Posterior gonopod coxites (pgc, Figs. 240, 241, 249, 250) short, broad, anteriorly cupped, with two curved processes distolaterally, two smaller processes arising from anterior face of body of coxite. Coxae 10 and eleventh prefemora typical of family. Female 5.0 mm long, nonsexual characters as in male.

Reduced Complexity In-Phase/Quadrature-Phase M-QAM Turbo Equalization Using Iterative Channel Estimation
No full textA reduced complexity trellis-based turbo equalizer known as the in-phase (I)/quadrature-phase (Q) turbo equalizer (TEQ-IQ) invoking iterative channel impulse response (CIR) estimation is proposed. The underlying principle of TEQ-IQ is based on equalizing the I and Q component of the transmitted signal independently. This requires the equalization of a reduced set of separate I and Q signal components in comparison to all of the possible I/Q phasor combinations considered by the conventional trellis-based equalizer. It was observed that the TEQ-IQ operating in conjunction with iterative CIR estimation was capable of achieving the same performance as the full-complexity conventional turbo equalizer (TEQ-CT) benefiting from perfect CIR information for both 4- and 16-quadrature amplitude modulation (QAM) transmissions, while attaining a complexity reduction factor of 1.1 and 12.2, respectively. For 64-QAM, the TEQ-CT receiver was too complex to be investigated by simulation. However, by assuming that only two turbo equalization iterations were required, which is the lowest possible number of iterations, the complexity of the TEQ-IQ was estimated to be a factor of 51.5 lower than that of the TEQ-CT. Furthermore, at BER = 10-3 the performance of the TEQ-IQ 64-QAM receiver using iterative CIR estimation was only 1.5 dB away from the associated decoding performance curve of the nondispersive Gaussian channel. <br/
